Update the __gitcomp_directories method to de-quote and handle unusual
characters in directory names. Although this initially involved an attempt
to re-use the logic in __git_index_files, this method removed
subdirectories (e.g. folder1/0/ became folder1/), so instead new custom
logic was placed directly in the __gitcomp_directories method.
Note there are two tests for this new functionality - one for spaces and
accents and one for backslashes and tabs. The backslashes and tabs test
uses FUNNYNAMES to avoid running on Windows. This is because:
1. Backslashes are explicitly not allowed in Windows file paths.
2. Although tabs appear to be allowed when creating a file in a Windows
bash shell, they actually are not renderable (and appear as empty boxes
in the shell).

Use new __gitcomp_directories method to complete directory names in cone

Correct multiple issues with tab completion of the git sparse-checkout
command. These issues were:
1. git sparse-checkout <TAB> previously resulted in an incomplete list of
subcommands (it was missing reapply and add).
2. Subcommand options were not tab-completable.
3. git sparse-checkout set <TAB> and git sparse-checkout add <TAB> showed
both file names and directory names. While this may be a less surprising
behavior for non-cone mode, cone mode sparse checkouts should complete
only directory names.
Note that while the new strategy of just using git ls-tree to complete on
directory names is simple and a step in the right direction, it does have
some caveats. These are:
1. Likelihood of poor performance in large monorepos (as a result of
recursively completing directory names).
2. Inability to handle paths containing unusual characters.
These caveats will be fixed by subsequent commits in this series.

Add a GIT_COMPLETION_SHOW_ALL_COMMANDS=1 configuration setting to go
with the existing GIT_COMPLETION_SHOW_ALL=1 added in
c099f579b98 (completion: add GIT_COMPLETION_SHOW_ALL env var,
2020-08-19).
This will include plumbing commands such as "cat-file" in "git <TAB>"
and "git c<TAB>" completion. Without/with this I have 134 and 243
completion with git <TAB>, respectively.
It was already possible to do this by tweaking
GIT_TESTING_PORCELAIN_COMMAND_LIST= from the outside, that testing
variable was added in 84a97131065 (completion: let git provide the
completable command list, 2018-05-20). Doing this before loading
git-completion.bash worked:
export GIT_TESTING_PORCELAIN_COMMAND_LIST="$(git --list-cmds=builtins,main,list-mainporcelain,others,nohelpers,alias,list-complete,config)"
But such testing variables are not meant to be used from the outside,
and we make no guarantees that those internal won't change. So let's
expose this as a dedicated configuration knob.
It would be better to teach --list-cmds=* a new category which would
include all of these groups, but that's a larger change that we can
leave for some other time.

Change tests of git-completion.bash that re-source it to do so inside
a subshell. Re-sourcing it will clobber variables it sets, and in the
case of the "GIT_COMPLETION_SHOW_ALL=1" test added in
ca2d62b7879 (parse-options: don't complete option aliases by default,
2021-07-16) change the behavior of the completion persistently.
Aside from the addition of "(" and ")" on new lines this is an
indentation-only change, only the "(" and ")" lines are changed under
"git diff -w".
So let's change that test, and for good measure do the same for the
three tests that precede it, which were added in
8b0eaa41f23 (completion: clear cached --options when sourcing the
completion script, 2018-03-22). The may not be wrong, but doing this
establishes a more reliable pattern for future tests, which might use
these as a template to copy.

Many invocations of the test_expect_success command in this
file are written in old style where the command, an optional
prerequisite, and the test title are written on separate
lines, and the executable script string begins on its own
line, and these lines are pasted together with backslashes
as necessary.
An invocation of the test_expect_success command in modern
test scripts however writes the prerequisite and the title
on the same line as the test_expect_success command itself,
and ends the line with a single quote that begins the
executable script string.
Update the style for uniformity.

Normally diffs will contain a hunk header of the format
"@@ -2,2 +2,15 @@ code". However when there is only 1 line of
change, the unified diff format allows for the second comma
separated value to be omitted in either before or after
line counts.
This can produce hunk headers that look like
"@@ -2 +2,18 @@ code" or "@@ -2,2 +2 @@ code".
As a result, scan_hunk_header mistakenly returns the line
number as line count, which then results in unpredictable
parsing errors with the rest of the patch, including giving
multiple lines of output for a single commit.
Fix by explicitly setting line count to 1 when there is
no comma, and add a test.
apply.c contains this same logic except it is correct. A
worthwhile future project might be to unify these two diff
parsers so they both benefit from fixes.

Doing diffs for merges are special; they should typically avoid history
simplification. For example, with
git log --diff-merges=first-parent -- path
the default history simplification would remove merge commits from
consideration if the file "path" matched the second parent. That is
counter to what the user wants when looking for first-parent diffs.
Similar comments can be made for --diff-merges=separate (which diffs
against both parents) and --diff-merges=remerge (which diffs against a
remerge of the merge commit).
However, history simplification still makes sense if not doing diffing
merges, and it also makes sense for the combined and dense-combined
forms of diffing merges (because both of those are defined to only show
a diff when the merge result at the relevant paths differs from *both*
parents).
So, for separate, first-parent, and remerge styles of diff-merges, turn
off history simplification.

Conflicts such as modify/delete, rename/rename, or file/directory are
not representable via content conflict markers, and the normal output
messages notifying users about these were dropped with --remerge-diff.
While we don't want these messages randomly shown before the commit
and diff headers, we do want them to still be shown; include them as
part of the diff headers instead.

Instead of immediately printing ll-merge warnings to stderr, we save
them in our output strbuf. Besides allowing us to move these warnings
to a special file for --remerge-diff, this has two other benefits for
regular merges done by merge-ort:
* The deferral of messages ensures we can print all messages about
any given path together (merge-recursive was known to sometimes
intersperse messages about other paths, particularly when renames
were involved).
* The deferral of messages means we can avoid printing spurious
conflict messages when we just end up aborting due to local user
modifications in the way. (In contrast to merge-recursive.c which
prematurely checks for local modifications in the way via
unpack_trees() and gets the check wrong both in terms of false
positives and false negatives relative to renames, merge-ort does
not perform the local modifications in the way check until the
checkout() step after the full merge has been computed.)

When this option is specified, we remerge all (two parent) merge commits
and diff the actual merge commit to the automatically created version,
in order to show how users removed conflict markers, resolved the
different conflict versions, and potentially added new changes outside
of conflict regions in order to resolve semantic merge problems (or,
possibly, just to hide other random changes).
This capability works by creating a temporary object directory and
marking it as the primary object store. This makes it so that any blobs
or trees created during the automatic merge are easily removable
afterwards by just deleting all objects from the temporary object
directory.
There are a few ways that this implementation is suboptimal:
* `log --remerge-diff` becomes slow, because the temporary object
directory can fill with many loose objects while running
* the log output can be muddied with misplaced "warning: cannot merge
binary files" messages, since ll-merge.c unconditionally writes those
messages to stderr while running instead of allowing callers to
manage them.
* important conflict and warning messages are simply dropped; thus for
conflicts like modify/delete or rename/rename or file/directory which
are not representable with content conflict markers, there may be no
way for a user of --remerge-diff to know that there had been a
conflict which was resolved (and which possibly motivated other
changes in the merge commit).
* when fixing the previous issue, note that some unimportant conflict
and warning messages might start being included. We should instead
make sure these remain dropped.
Subsequent commits will address these issues.

In commit af3a67de01 ("negotiator: unknown fetch.negotiationAlgorithm

fetch.negotiationAlgorithm was added with the code die()ing. This was
also added to the documentation for the fetch.negotiationAlgorithm
option, to make it explicit that the code would die on unknown values.

behavior again matches the documentation.

In commit 3050b6dfc75d (repo-settings.c: simplify the setup,
2021-09-21), the branch for handling fetch.negotiationAlgorithm=default
was deleted. Since this value is documented in
Documentation/config/fetch.txt, restore the check for this value.
Note that this change caused an observable bug: if someone sets
feature.experimental=true in config, and then passes "-c
fetch.negotiationAlgorithm=default" on the command line in an attempt to
override the config, then the override is ignored. Fix the bug by not
ignoring the value of "default".
Technically, before commit 3050b6dfc75d, repo-settings would treat any
fetch.negotiationAlgorithm value other than "skipping" or "noop" as a
request for "default", but I think it probably makes more sense to
ignore such broken requests and leave fetch.negotiationAlgorithm with
the default value rather than the value of "default". (If that sounds
confusing, note that "default" is usually the default value, but when
feature.experimental=true, "skipping" is the default value.)

Fix misbehavior in Git.pm that dates back to the very first version of
the library in git.git added in b1edc53d062 (Introduce Git.pm (v4),
2006-06-24). When we fail to execute a command we shouldn't ignore all
signals, those can happen e.g. if abort() is called, or if the command
segfaults.
Because of this we'd consider e.g. a command that died due to LSAN
exiting with abort() successful, as is the case with the tests listed
as running successfully with SANITIZE=leak in 9081a421a6d (checkout:
fix "branch info" memory leaks, 2021-11-16). We did run them
successfully, but only because we ignored these errors.
This was then made worse by the use of "abort_on_error=1" for LSAN
added in 85b81b35ff9 (test-lib: set LSAN_OPTIONS to abort by default,
2017-09-05). Doing that makes sense, but without providing that option
we'd have a "$? >> 8" of "23" on failure, with abort_on_error=1 we'll
get "0".
All of our tests pass even without the SIGPIPE exception being added
here, but as the code appears to have been trying to ignore it let's
keep ignoring it for now.
