For the same reasons as the prior change we want to allow frontends
to omit the trailing LF that usually delimits commands. In some
cases these just make the input stream more verbose looking than
it needs to be, and its just simpler for the frontend developer to
get started if our parser is slightly more lenient about where an
LF is required and where it isn't.
To make this optional LF feature work we now have to buffer up to one
line of input in command_buf. This buffering can happen if we look
at the current input command but don't recognize it at this point
in the code. In such a case we need to "unget" the entire line,
but we cannot depend upon the stdio library to let us do ungetc()
for that many characters at once.

A few fast-import frontend developers have found it odd that we
require the LF following a `data` command, especially in the exact
byte count format. Technically we don't need this LF to parse
the stream properly, but having it here does make the stream more
readable to humans. We can easily make the LF optional by peeking
at the next byte available from the stream and pushing it back into
the buffer if its not LF.

Several frontend developers have asked that some form of stream
comments be permitted within a fast-import data stream. This way
they can include information from their own frontend program about
where specific data was taken from in the source system, or about
a decision that their frontend may have made while creating the
fast-import data stream.
This change introduces comments in the Bourne-shell/Tcl/Perl style.
Lines starting with '#' are ignored, up to and including the LF.
Unlike the above mentioned three languages however we do not look for
and ignore leading whitespace. This just simplifies the definition
of the comment format and the code that parses them.
To make comments work we had to stop using read_next_command() within
cmd_data() and directly invoke read_line() during the inline variant
of the function. This is necessary to retain any lines of the
input data that might otherwise look like a comment to fast-import.

Instead of growing our buffer by hand during the inline variant of
cmd_data() we can save a few lines of code and just use the nifty
new ALLOC_GROW macro already available to us.

Michael Haggerty <mhagger@alum.mit.edu> noticed while debugging a
Git backend for cvs2svn that fast-import was barfing when he tried
to use "TAG_FIXUP" as a branch name for temporary work needed to
cleanup the tree prior to creating an annotated tag object.
The reason we were rejecting the branch name was check_ref_format()
returns -2 when there are less than 2 '/' characters in the input
name. TAG_FIXUP has 0 '/' characters, but is technically just as
valid of a ref as HEAD and MERGE_HEAD, so we really should permit it
(and any other similar looking name) during import.
New test cases have been added to make sure we still detect very
wrong branch names (e.g. containing [ or starting with .) and yet
still permit reasonable names (e.g. TAG_FIXUP).

git-add -u paths... now works from subdirectory
Fix "git add -u" data corruption.
|

For multi-base merges, we allowed read-tree -m to take more than
three trees (the last two are our and their branches, and all the
earlier ones, typically one but potentially more, are used as the
merge base). Unfortunately, the conversion done by commit 933bf40

This applies to 'maint' to fix a rather serious data corruption
issue. When "git add -u" affects a subdirectory in such a way
that the only changes to its contents are path removals, the
next tree object written out of that index was bogus, as the
remove codepath forgot to invalidate the cache-tree entry.

This makes .gitattributes files to be read from the index when
they are not checked out to the work tree. This is in line with
the way we always allowed low-level tools to operate in sparsely
checked out work tree in a reasonable way.
It swaps the order of new file creation and converting the blob
to work tree representation; otherwise when we are in the middle
of checking out .gitattributes we would notice an empty but
unwritten .gitattributes file in the work tree and will ignore
the copy in the index.

This splits out a common routine that parses a single line of
attribute file and adds it to the attr_stack. It should not
change any behaviour, other than attrs array in the attr_stack
structure is now grown with alloc_nr() macro, instead of one by
one, which relied on xrealloc() to give enough slack to be
efficient enough.

When we compare two non-tracked files, or explicitly
specify --no-index, the suggestion to run git-status
is not helpful.
The patch adds a new diff_options bitfield member, no_index, that
is used instead of the special value of -2 of the rev_info field
max_count to indicate that the index is not to be used. This makes
it possible to pass that flag down to diffcore_skip_stat_unmatch(),
which only has one diff_options parameter.
This could even become a cleanup if we removed all assignments of
max_count to a value of -2 (viz. replacement of a magic value with
a self-documenting field name) but I didn't dare to do that so late
in the rc game..
The no_index bit, if set, then tells diffcore_skip_stat_unmatch()
to not account for any skipped stat-mismatches, which avoids the
suggestion to run git-status.

When you try to merge a path that involves binary file-level
merge, merge-recursive died rudely without cleaning up its own
mess. A files added by the merge were left in the working tree,
but the index was not written out (because it just punted and
died), so it was cumbersome for the user to retry it by first
running "git reset --hard".
This changes merge-recursive to still warn but do the "binary"
merge for such a path; leave the "our" version in the working
tree, but still keep the path unmerged so that the user can sort
it out.

After starting to edit a working tree file but later when your edit ends
up identical to the original (this can also happen when you ran a
wholesale regexp replace with something like "perl -i" that does not
actually modify many of the paths), "git diff" between the index and the
working tree outputs many "empty" diffs that show "diff --git" headers
and nothing else, because these paths are stat-dirty. While it was a
way to warn the user that the earlier action of the user made the index
ineffective as an optimization mechanism, it was felt too loud for the
purpose of warning even to experienced users, and also resulted in
confusing people new to git.
This replaces the "empty" diffs with a single warning message at the
end. Having many such paths hurts performance, and you can run
"git-update-index --refresh" to update the lstat(2) information recorded
in the index in such a case. "git-status" does so as a side effect, and
that is more familiar to the end-user, so we recommend it to them.
The change affects only "git diff" that outputs patch text, because that
is where the annoyance of too many "empty" diff is most strongly felt,
and because the warning message can be safely ignored by downstream
tools without getting mistaken as part of the patch. For the low-level
"git diff-files" and "git diff-index", the traditional behaviour is
retained.

Quite a few of the scripts are rather careless about using GIT_DIR
while changing directories.
Some try their hands (with different likelihood of success) in making
GIT_DIR absolute.
This patch lets git-sh-setup.sh cater for absolute directories (in a
way that should work reliably also with non-Unix path names) and
removes the respective kludges in git-filter-branch.sh and
git-instaweb.sh.

Some repositories started with the trunk in "/" and then moved it to the
standard "trunk/" location.
On these repositories, the correct thing would be to call git-svnimport -T "",
but because of the way the options are handled, it uses the default "trunk"
instead of the given empty string. This patch fixes that behaviour.

When performing a git-p4 clone operation on a Perforce repository,
where the changelists change in order of magnitude (e.g. 100 to 1000),
the set of changes to import from is not sorted properly. This is
because the data in the list is strings not integers. The other place
where this is done already converts the value to an integer, so it is
not affected.

As Wincent Colaiuta found out, it's a bit unexpected for git diff to
start a pager even when the --quiet option is specified. The problem
is that the pager hides the return code -- which is the only output
we're interested in in this case.
Push pager setup down into builtin-diff.c and don't start the pager
if --exit-code or --quiet (which implies --exit-code) was specified.
