2016-12-14i18n: add--interactive: mark status words for translationLibravatar Vasco Almeida1-6/+6
Mark words 'nothing', 'unchanged' and 'binary' used to display what has been staged or not, in "git add -i" status command. Alternatively one could mark N__('nothing') no-op in order to xgettext(1) extract the string and then trigger the translation at run time only with __($print->{FILE}), but that has the side effect of triggering retrieval of translations for the changes indicator too (e.g. +2/-1) which may or may not be a problem. To avoid that potential problem, mark only where there is certain to trigger translation only of those words but in this case we must also retrieve the translation for the eq tests, since the value assigned was of the translation, not the English source.

Mark message of edit_hunk_manually displayed in the editing file when user chooses 'e' option. The message had to be unfolded to allow translation of the $participle verb. Some messages end up being exactly the same for some use cases, but left it for easier change in the future, e.g., wanting to change wording of one particular use case.

2016-12-14i18n: add--interactive: mark patch prompt for translationLibravatar Vasco Almeida1-8/+46
Mark prompt message assembled in place for translation, unfolding each use case for each entry in the %patch_modes hash table. Previously, this script relied on whether $patch_mode was set to run the command patch_update_cmd() or show status and loop the main loop. Now, it uses $cmd to indicate we must run patch_update_cmd() and $patch_mode is used to tell which flavor of the %patch_modes are we on. This is introduced in order to be able to mark and unfold the message prompt knowing in which context we are. The tracking of context was done previously by point %patch_mode_flavour hash table to the correct entry of %patch_modes, focusing only on value of %patch_modes. Now, we are also interested in the key ('staged', 'stash', 'checkout_head', ...). Signed-off-by: Vasco Almeida <vascomalmeida@sapo.pt> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-12-14i18n: add--interactive: mark simple here-documents for translationLibravatar Vasco Almeida1-3/+5
Mark messages in here-documents without interpolation for translation. The here-document delimiter \EOF, which is the same as 'EOF', indicates that the text is to be treated literally without interpolation of its content. Unfortunately xgettext is not able to extract here-documents delimited with \EOF but it is with delimiter enclosed in single quotes. So change \EOF to 'EOF', although in this case does not make difference what variation of here-document to use since there is nothing to interpolate.

2016-09-19diff: improve positioning of add/delete blocks in diffsLibravatar Michael Haggerty1-1/+4
Some groups of added/deleted lines in diffs can be slid up or down, because lines at the edges of the group are not unique. Picking good shifts for such groups is not a matter of correctness but definitely has a big effect on aesthetics. For example, consider the following two diffs. The first is what standard Git emits: --- a/9c572b21dd090a1e5c5bb397053bf8043ffe7fb4:git-send-email.perl +++ b/6dcfa306f2b67b733a7eb2d7ded1bc9987809edb:git-send-email.perl @@ -231,6 +231,9 @@ if (!defined $initial_reply_to && $prompting) { } if (!$smtp_server) { + $smtp_server = $repo->config('sendemail.smtpserver'); +} +if (!$smtp_server) { foreach (qw( /usr/sbin/sendmail /usr/lib/sendmail )) { if (-x $_) { $smtp_server = $_; The following diff is equivalent, but is obviously preferable from an aesthetic point of view: --- a/9c572b21dd090a1e5c5bb397053bf8043ffe7fb4:git-send-email.perl +++ b/6dcfa306f2b67b733a7eb2d7ded1bc9987809edb:git-send-email.perl @@ -230,6 +230,9 @@ if (!defined $initial_reply_to && $prompting) { $initial_reply_to =~ s/(^\s+|\s+$)//g; } +if (!$smtp_server) { + $smtp_server = $repo->config('sendemail.smtpserver'); +} if (!$smtp_server) { foreach (qw( /usr/sbin/sendmail /usr/lib/sendmail )) { if (-x $_) { This patch teaches Git to pick better positions for such "diff sliders" using heuristics that take the positions of nearby blank lines and the indentation of nearby lines into account. The existing Git code basically always shifts such "sliders" as far down in the file as possible. The only exception is when the slider can be aligned with a group of changed lines in the other file, in which case Git favors depicting the change as one add+delete block rather than one add and a slightly offset delete block. This naive algorithm often yields ugly diffs. Commit d634d61ed6 improved the situation somewhat by preferring to position add/delete groups to make their last line a blank line, when that is possible. This heuristic does more good than harm, but (1) it can only help if there are blank lines in the right places, and (2) always picks the last blank line, even if there are others that might be better. The end result is that it makes perhaps 1/3 as many errors as the default Git algorithm, but that still leaves a lot of ugly diffs. This commit implements a new and much better heuristic for picking optimal "slider" positions using the following approach: First observe that each hypothetical positioning of a diff slider introduces two splits: one between the context lines preceding the group and the first added/deleted line, and the other between the last added/deleted line and the first line of context following it. It tries to find the positioning that creates the least bad splits. Splits are evaluated based only on the presence and locations of nearby blank lines, and the indentation of lines near the split. Basically, it prefers to introduce splits adjacent to blank lines, between lines that are indented less, and between lines with the same level of indentation. In more detail: 1. It measures the following characteristics of a proposed splitting position in a `struct split_measurement`: * the number of blank lines above the proposed split * whether the line directly after the split is blank * the number of blank lines following that line * the indentation of the nearest non-blank line above the split * the indentation of the line directly below the split * the indentation of the nearest non-blank line after that line 2. It combines the measured attributes using a bunch of empirically-optimized weighting factors to derive a `struct split_score` that measures the "badness" of splitting the text at that position. 3. It combines the `split_score` for the top and the bottom of the slider at each of its possible positions, and selects the position that has the best `split_score`. I determined the initial set of weighting factors by collecting a corpus of Git histories from 29 open-source software projects in various programming languages. I generated many diffs from this corpus, and determined the best positioning "by eye" for about 6600 diff sliders. I used about half of the repositories in the corpus (corresponding to about 2/3 of the sliders) as a training set, and optimized the weights against this corpus using a crude automated search of the parameter space to get the best agreement with the manually-determined values. Then I tested the resulting heuristic against the full corpus. The results are summarized in the following table, in column `indent-1`: | repository | count | Git 2.9.0 | compaction | compaction-fixed | indent-1 | indent-2 | | --------------------- | ----- | -------------- | -------------- | ---------------- | -------------- | -------------- | | afnetworking | 109 | 89 (81.7%) | 37 (33.9%) | 37 (33.9%) | 2 (1.8%) | 2 (1.8%) | | alamofire | 30 | 18 (60.0%) | 14 (46.7%) | 15 (50.0%) | 0 (0.0%) | 0 (0.0%) | | angular | 184 | 127 (69.0%) | 39 (21.2%) | 23 (12.5%) | 5 (2.7%) | 5 (2.7%) | | animate | 313 | 2 (0.6%) | 2 (0.6%) | 2 (0.6%) | 2 (0.6%) | 2 (0.6%) | | ant | 380 | 356 (93.7%) | 152 (40.0%) | 148 (38.9%) | 15 (3.9%) | 15 (3.9%) | * | bugzilla | 306 | 263 (85.9%) | 109 (35.6%) | 99 (32.4%) | 14 (4.6%) | 15 (4.9%) | * | corefx | 126 | 91 (72.2%) | 22 (17.5%) | 21 (16.7%) | 6 (4.8%) | 6 (4.8%) | | couchdb | 78 | 44 (56.4%) | 26 (33.3%) | 28 (35.9%) | 6 (7.7%) | 6 (7.7%) | * | cpython | 937 | 158 (16.9%) | 50 (5.3%) | 49 (5.2%) | 5 (0.5%) | 5 (0.5%) | * | discourse | 160 | 95 (59.4%) | 42 (26.2%) | 36 (22.5%) | 18 (11.2%) | 13 (8.1%) | | docker | 307 | 194 (63.2%) | 198 (64.5%) | 253 (82.4%) | 8 (2.6%) | 8 (2.6%) | * | electron | 163 | 132 (81.0%) | 38 (23.3%) | 39 (23.9%) | 6 (3.7%) | 6 (3.7%) | | git | 536 | 470 (87.7%) | 73 (13.6%) | 78 (14.6%) | 16 (3.0%) | 16 (3.0%) | * | gitflow | 127 | 0 (0.0%) | 0 (0.0%) | 0 (0.0%) | 0 (0.0%) | 0 (0.0%) | | ionic | 133 | 89 (66.9%) | 29 (21.8%) | 38 (28.6%) | 1 (0.8%) | 1 (0.8%) | | ipython | 482 | 362 (75.1%) | 167 (34.6%) | 169 (35.1%) | 11 (2.3%) | 11 (2.3%) | * | junit | 161 | 147 (91.3%) | 67 (41.6%) | 66 (41.0%) | 1 (0.6%) | 1 (0.6%) | * | lighttable | 15 | 5 (33.3%) | 0 (0.0%) | 2 (13.3%) | 0 (0.0%) | 0 (0.0%) | | magit | 88 | 75 (85.2%) | 11 (12.5%) | 9 (10.2%) | 1 (1.1%) | 0 (0.0%) | | neural-style | 28 | 0 (0.0%) | 0 (0.0%) | 0 (0.0%) | 0 (0.0%) | 0 (0.0%) | | nodejs | 781 | 649 (83.1%) | 118 (15.1%) | 111 (14.2%) | 4 (0.5%) | 5 (0.6%) | * | phpmyadmin | 491 | 481 (98.0%) | 75 (15.3%) | 48 (9.8%) | 2 (0.4%) | 2 (0.4%) | * | react-native | 168 | 130 (77.4%) | 79 (47.0%) | 81 (48.2%) | 0 (0.0%) | 0 (0.0%) | | rust | 171 | 128 (74.9%) | 30 (17.5%) | 27 (15.8%) | 16 (9.4%) | 14 (8.2%) | | spark | 186 | 149 (80.1%) | 52 (28.0%) | 52 (28.0%) | 2 (1.1%) | 2 (1.1%) | | tensorflow | 115 | 66 (57.4%) | 48 (41.7%) | 48 (41.7%) | 5 (4.3%) | 5 (4.3%) | | test-more | 19 | 15 (78.9%) | 2 (10.5%) | 2 (10.5%) | 1 (5.3%) | 1 (5.3%) | * | test-unit | 51 | 34 (66.7%) | 14 (27.5%) | 8 (15.7%) | 2 (3.9%) | 2 (3.9%) | * | xmonad | 23 | 22 (95.7%) | 2 (8.7%) | 2 (8.7%) | 1 (4.3%) | 1 (4.3%) | * | --------------------- | ----- | -------------- | -------------- | ---------------- | -------------- | -------------- | | totals | 6668 | 4391 (65.9%) | 1496 (22.4%) | 1491 (22.4%) | 150 (2.2%) | 144 (2.2%) | | totals (training set) | 4552 | 3195 (70.2%) | 1053 (23.1%) | 1061 (23.3%) | 86 (1.9%) | 88 (1.9%) | | totals (test set) | 2116 | 1196 (56.5%) | 443 (20.9%) | 430 (20.3%) | 64 (3.0%) | 56 (2.6%) | In this table, the numbers are the count and percentage of human-rated sliders that the corresponding algorithm got *wrong*. The columns are * "repository" - the name of the repository used. I used the diffs between successive non-merge commits on the HEAD branch of the corresponding repository. * "count" - the number of sliders that were human-rated. I chose most, but not all, sliders to rate from those among which the various algorithms gave different answers. * "Git 2.9.0" - the default algorithm used by `git diff` in Git 2.9.0. * "compaction" - the heuristic used by `git diff --compaction-heuristic` in Git 2.9.0. * "compaction-fixed" - the heuristic used by `git diff --compaction-heuristic` after the fixes from earlier in this patch series. Note that the results are not dramatically different than those for "compaction". Both produce non-ideal diffs only about 1/3 as often as the default `git diff`. * "indent-1" - the new `--indent-heuristic` algorithm, using the first set of weighting factors, determined as described above. * "indent-2" - the new `--indent-heuristic` algorithm, using the final set of weighting factors, determined as described below. * `*` - indicates that repo was part of training set used to determine the first set of weighting factors. The fact that the heuristic performed nearly as well on the test set as on the training set in column "indent-1" is a good indication that the heuristic was not over-trained. Given that fact, I ran a second round of optimization, using the entire corpus as the training set. The resulting set of weights gave the results in column "indent-2". These are the weights included in this patch. The final result gives consistently and significantly better results across the whole corpus than either `git diff` or `git diff --compaction-heuristic`. It makes only about 1/30 as many errors as the former and about 1/10 as many errors as the latter. (And a good fraction of the remaining errors are for diffs that involve weirdly-formatted code, sometimes apparently machine-generated.) The tools that were used to do this optimization and analysis, along with the human-generated data values, are recorded in a separate project [1]. This patch adds a new command-line option `--indent-heuristic`, and a new configuration setting `diff.indentHeuristic`, that activate this heuristic. This interface is only meant for testing purposes, and should be finalized before including this change in any release.

2016-02-28add--interactive: allow custom diff highlighting programsLibravatar Jeff King1-2/+10
The patch hunk selector of add--interactive knows how ask git for colorized diffs, and correlate them with the uncolored diffs we apply. But there's not any way for somebody who uses a diff-filter tool like contrib's diff-highlight to see their normal highlighting. This patch lets users define an arbitrary shell command to pipe the colorized diff through. The exact output shouldn't matter (since we just show the result to humans) as long as it is line-compatible with the original diff (so that hunk-splitting can split the colorized version, too). I left two minor issues with the new system that I don't think are worth fixing right now, but could be done later: 1. We only filter colorized diffs. Theoretically a user could want to filter a non-colorized diff, but I find it unlikely in practice. Users who are doing things like diff-highlighting are likely to want color, too. 2. add--interactive will re-colorize a diff which has been hand-edited, but it won't have run through the filter. Fixing this is conceptually easy (just pipe the diff through the filter), but practically hard to do without using tempfiles (it would need to feed data to and read the result from the filter without deadlocking; this raises portability questions with respect to Windows). I've punted on both issues for now, and if somebody really cares later, they can do a patch on top. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The interactive "show a list and let the user choose from it" interface "add -i" used showed and prompted to the user even when the candidate list was empty, against which the only "choice" the user could have made was to choose nothing. * ak/add-i-empty-candidates: add -i: return from list_and_choose if there is no candidate
2015-01-22add -i: return from list_and_choose if there is no candidateLibravatar Alexander Kuleshov1-0/+5
The list_and_choose() helper is given a prompt and a list, asks the user to make selection from the list, and then returns a list of items chosen. Even when it is given an empty list as the original candidate set to choose from, it gave a prompt to the user, who can only say "I am done choosing". Return an empty result when the input is an empty list without bothering the user. The existing caller must already have a logic to say "Nothing to do" or an equivalent when the returned list is empty (i.e. the user chose to select nothing) if it is necessary, so no change to the callers is necessary. This fixes the case where "add untracked" is asked in "git add -i" and there is no untracked files in the working tree. We used to give an empty list of files to choose from with a prompt, but with this change, we no longer do.

2014-12-15add--interactive: leave main loop on read errorLibravatar Jeff King1-0/+1
The main hunk loop for add--interactive will loop if it does not get a known input. This is a good thing if the user typed some invalid input. However, if we have an uncorrectable read error, we'll end up looping infinitely. We can fix this by noticing read errors (i.e., <STDIN> returns undef) and breaking out of the loop. One easy way to trigger this is if you have an editor that does not take over the terminal (e.g., one that spawns a window in an existing process and waits), start the editor with the hunk-edit command, and hit ^C to send SIGINT. The editor process dies due to SIGINT, but the perl add--interactive process does not (perl suspends SIGINT for the duration of our system() call). We return to the main loop, but further reads from stdin don't work. The SIGINT _also_ killed our parent git process, which orphans our process group, meaning that further reads from the terminal will always fail. We loop infinitely, getting EIO on each read. Note that there are several other spots where we read from stdin, too. However, in each of those cases, we do something sane when the read returns undef (breaking out of the loop, taking the input as "no", etc). They don't need similar treatment.

Back in 21e9757e (Hack git-add--interactive to make it work with ActiveState Perl, 2007-08-01), the invocation of external commands was changed to use qx{} on Windows. The rationale was that the command interpreter on Windows is not a POSIX shell, but rather Windows's CMD. That patch was wrong to include 'msys' in the check whether to use qx{} or not: 'msys' identifies MSYS perl as shipped with Git for Windows, which does not need the special treatment; qx{} should be used only with ActiveState perl, which is identified by 'MSWin32'.

2013-06-12add--interactive: respect diff.algorithmLibravatar John Keeping1-0/+5
When staging hunks interactively it is sometimes useful to use an alternative diff algorithm which splits the changes into hunks in a more logical manner. This is not possible because the plumbing commands called by add--interactive ignore the "diff.algorithm" configuration option (as they should). Since add--interactive is a porcelain command it should respect this configuration variable. To do this, make it read diff.algorithm and pass its value to the underlying diff-index and diff-files invocations. At this point, do not add options to "git add", "git reset" or "git checkout" (all of which can call git-add--interactive). If a user wants to override the value on the command line they can use: git -c diff.algorithm=$ALGO ...

When "add -p" sees an unmerged entry, it shows the combined diff and then immediately skips the hunk. This can be confusing in a variety of ways, depending on whether there are other changes to stage (in which case you get the superfluous combined diff output in between other hunks) or not (in which case you get the combined diff and the program exits immediately, rather than seeing "No changes"). The current behavior was not planned, and is just what the implementation happens to do. Instead, let's explicitly remove unmerged entries from our list of modified files, and print a warning that we are ignoring them. We can cheaply find which entries are unmerged by adding "--raw" output to the "diff-files --numstat" we already run. There is one non-obvious thing we must change when parsing this combined output. Before this patch, when we saw a numstat line for a file that did not have index changes, we would create a new record with 'unchanged' in the 'INDEX' field. Because "--raw" comes before "--numstat", we must move this special-case down to the raw-line case (and it is sufficient to move it rather than handle it in both places, since any file which has a --numstat will also have a --raw entry).

2011-05-17add -i: ignore terminal escape sequencesLibravatar Thomas Rast1-0/+19
On the author's terminal, the up-arrow input sequence is ^[[A, and thus fat-fingering an up-arrow into 'git checkout -p' is quite dangerous: git-add--interactive.perl will ignore the ^[ and [ characters and happily treat A as "discard everything". As a band-aid fix, use Term::Cap to get all terminal capabilities. Then use the heuristic that any capability value that starts with ^[ (i.e., \e in perl) must be a key input sequence. Finally, given an input that starts with ^[, read more characters until we have read a full escape sequence, then return that to the caller. We use a timeout of 0.5 seconds on the subsequent reads to avoid getting stuck if the user actually input a lone ^[. Since none of the currently recognized keys start with ^[, the net result is that the sequence as a whole will be ignored and the help displayed.

2011-04-29"add -p": work-around an old laziness that does not coalesce hunksLibravatar Junio C Hamano1-1/+1
Since 0beee4c (git-add--interactive: remove hunk coalescing, 2008-07-02), "git add--interactive" behaves lazily and passes overlapping hunks to the underlying "git apply" without coalescing. This was partially corrected by 7a26e65 (its partial revert, 2009-05-16), but overlapping hunks are still passed when the patch is edited. Teach "git apply" the --allow-overlap option that disables a safety feature that avoids misapplication of patches by not applying patches to overlapping hunks, and pass this option form "add -p" codepath. Do not even advertise the option, as this is merely a workaround, and the correct fix is to make "add -p" correctly coalesce adjacent patch hunks. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-04-29add--interactive.perl: factor out repeated --recount optionLibravatar Junio C Hamano1-8/+8
Depending on the direction and the target of patch application, we would need to pass --cached and --reverse to underlying "git apply". Also we only pass --check when we are not applying but just checking. But we always pass --recount since 8cbd431 (git-add--interactive: replace hunk recounting with apply --recount, 2008-07-02). Instead of repeating the same --recount over and over again, move it to a single place that actually runs the command, namely, "run_git_apply" subroutine.

The "quit" command was added in 9a7a1e0 (git add -p: new "quit" command at the prompt, 2009-04-10) to allow the user to say that hunks other than what have already been chosen are undesirable, and exit the interactive loop immediately. It forgot that there may be an undecided hunk before the current one. In such a case, the interactive loop still goes back to the beginning. Clear all the USE bit for undecided hunks and exit the loop. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-09-27perl: use "use warnings" instead of -wLibravatar Ævar Arnfjörð Bjarmason1-1/+2
Change the Perl scripts to turn on lexical warnings instead of setting the global $^W variable via the -w switch. The -w sets warnings for all code that interpreter runs, while "use warnings" is lexically scoped. The former is probably not what the authors wanted. As an auxiliary benefit it's now possible to build Git with: PERL_PATH='/usr/bin/env perl' Which would previously result in failures, since "#!/usr/bin/env perl -w" doesn't work as a shebang.

2010-09-27perl: bump the required Perl version to 5.8 from 5.6.[21]Libravatar Ævar Arnfjörð Bjarmason1-0/+1
Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already used the three-arg form of open() which was introduced in 5.6.1, but t/t9700/test.pl explicitly depended on 5.6.2. However git-add--interactive.pl has been failing on the 5.6 line since it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open syntax: sub run_cmd_pipe { my $fh = undef; open($fh, '-|', @_) or die; return <$fh>; } Which when executed dies on "Can't use an undefined value as filehandle reference". Several of our tests also fail on 5.6 (even more when compiled with NO_PERL_MAKEMAKER=1): t2016-checkout-patch.sh t3904-stash-patch.sh t3701-add-interactive.sh t7105-reset-patch.sh t7501-commit.sh t9700-perl-git.sh Our code is bitrotting on 5.6 with no-one interested in fixing it, and pinning us to such an ancient release of Perl is keeping us from using useful features introduced in the 5.8 release. The 5.6 series is now over 10 years old, and the 5.6.2 maintenance release almost 7. 5.8 on the other hand is more than 8 years old. All the modern Unix-like operating systems have now upgraded to it or a later version, and 5.8 packages are available for old IRIX, AIX Solaris and Tru64 systems.

2010-06-13add-interactive: Clarify “remaining hunks in the file”Libravatar Jonathan Nieder1-3/+3
The "a" and "d" commands to ‘add --patch’ (accept/reject rest of file) interact with "j", "g", and "/" (skip some hunks) in a perhaps confusing way: after accepting or rejecting all _later_ hunks in the file, they return to the earlier, skipped hunks and prompt the user about them again. This behavior can be very useful in practice. One can still accept or reject _all_ undecided hunks in a file by using the "g" command to move to hunk #1 first.

2010-02-22add-interactive: fix bogus diff header line orderingLibravatar Jeff King1-1/+23
When we look at a patch for adding hunks interactively, we first split it into a header and a list of hunks. Some of the header lines, such as mode changes and deletion, however, become their own selectable hunks. Later when we reassemble the patch, we simply concatenate the header and the selected hunks. This leads to patches like this: diff --git a/file b/file index d95f3ad..0000000 --- a/file +++ /dev/null deleted file mode 100644 @@ -1 +0,0 @@ -content Notice how the deletion comes _after_ the ---/+++ lines, when it should come before. In many cases, we can get away with this as git-apply accepts the slightly bogus input. However, in the specific case of a deletion line that is being applied via "apply -R", this malformed patch triggers an assert in git-apply. This comes up when discarding a deletion via "git checkout -p". Rather than try to make git-apply accept our odd input, let's just reassemble the patch in the correct order.

2009-12-07add-interactive: fix deletion of non-empty filesLibravatar Jeff King1-1/+5
Commit 24ab81a fixed the deletion of empty files, but broke deletion of non-empty files. The approach it took was to factor out the "deleted" line from the patch header into its own hunk, the same way we do for mode changes. However, unlike mode changes, we only showed the special "delete this file" hunk if there were no other hunks. Otherwise, the user would annoyingly be presented with _two_ hunks: one for deleting the file and one for deleting the content. This meant that in the non-empty case, we forgot about the deleted line entirely, and we submitted a bogus patch to git-apply (with "/dev/null" as the destination file, but not marked as a deletion). Instead, this patch combines the file deletion hunk and the content deletion hunk (if there is one) into a single deletion hunk which is either staged or not.

2009-10-27add-interactive: handle deletion of empty filesLibravatar Jeff King1-5/+13
Usually we show deletion as a big hunk deleting all of the file's text. However, for files with no content, the diff shows just the 'deleted file mode ...' line. This patch cause "add -p" (and related commands) to recognize that line and explicitly ask about deleting the file. We only add the "stage this deletion" hunk for empty files, since other files will already ask about the big content deletion hunk. We could also change those files to simply display "stage this deletion", but showing the actual deleted content is probably what an interactive user wants.
