Currently, when using --dirstat-by-file, it first does the full --dirstat
analysis (using diffcore_count_changes()), and then resets 'damage' to 1,
if any damage was found by diffcore_count_changes().
But --dirstat-by-file is not interested in the file damage per se. It only
cares if the file changed at all. In that sense it only cares if the blob
object for a file has changed. We therefore only need to compare the
object names of each file pair in the diff queue and we can skip the
entire --dirstat analysis and simply set 'damage' to 1 for each entry
where the object name has changed.
This makes --dirstat-by-file faster, and also bypasses --dirstat's practice
of ignoring rearranged lines within a file.
The patch also contains an added testcase verifying that --dirstat-by-file
now detects changes that only rearrange lines within a file.

used the --reset parameter instead of "-m", which turns off

strbuf: add fixed-length version of add_wrapped_text
Starting with commit c793430 (Limit file descriptors used by packs,
2011-02-28), git uses getrlimit to tell how many file descriptors it
can use. Unfortunately it does not include the header declaring that
function, resulting in compilation errors:
sha1_file.c: In function 'open_packed_git_1':
sha1_file.c:718: error: storage size of 'lim' isn't known
sha1_file.c:721: warning: implicit declaration of function 'getrlimit'
sha1_file.c:721: error: 'RLIMIT_NOFILE' undeclared (first use in this function)
sha1_file.c:718: warning: unused variable 'lim'
The standard header to include for this is <sys/resource.h> (which on
some systems itself requires declarations from <sys/types.h> or
<sys/time.h>). Probably the problem was missed until now because in
current glibc sys/resource.h happens to be included by sys/wait.h.
MinGW does not provide sys/resource.h (and compat/mingw takes care of
providing getrlimit some other way), so add the missing #include to
the "#ifndef __MINGW32__" block in git-compat-util.h.

During a merge module_list returns conflicting submodules several times
(stage 1,2,3) which caused the submodules to be used multiple times in
git submodule init, sync, update and status command.
There are 5 callers of module_list; they all read (mode, sha1, stage,
path) tuple, and most of them care only about path. As a first level
approximation, it should be Ok (in the sense that it does not make things
worse than it currently is) to filter the duplicate paths from module_list
output, but some callers should change their behaviour when the merge in
the superproject still has conflicts.
Notice the higher-stage entries, and emit only one record from
module_list, but while doing so, mark the entry with "U" (not [0-3]) in
the $stage field and null out the SHA-1 part, as the object name for the
lowest stage does not give any useful information to the caller, and this
way any caller that uses the object name would hopefully barf. Then
update the codepaths for each subcommands this way:
- "update" should not touch the submodule repository, because we do not
know what commit should be checked out yet.
- "status" reports the conflicting submodules as 'U000...000' and does
not recurse into them (we might later want to make it recurse).
- The command called by "foreach" may want to do whatever it wants to do
by noticing the merged status in the superproject itself, so feed the
path to it from module_list as before, but only once per submodule.
- "init" and "sync" are unlikely things to do while the superproject is
still not merged, but as long as a submodule is there in $path, there
is no point skipping it. It might however want to take the merged
status of .gitmodules into account, but that is outside of the scope of
this topic.

Fractional timezones, like -0330 (NST used in Canada) or +0430
(Afghanistan, Iran DST), were not handled properly in parse_date; this
means values such as 'minute_local' and 'iso-tz' were not generated
correctly.
This was caused by two mistakes:
* sign of timezone was applied only to hour part of offset, and not
as it should be also to minutes part (this affected only negative
fractional timezones).
* 'int $h + $m/60' is 'int($h + $m/60)' and not 'int($h) + $m/60',
so fractional part was discarded altogether ($h is hours, $m is
minutes, which is always less than 60).
Note that positive fractional timezones +0430, +0530 and +1030 can be
found as authortime in git.git repository itself.
For example http://repo.or.cz/w/git.git/commit/88d50e7 had authortime
of "Fri, 8 Jan 2010 18:48:07 +0000 (23:48 +0530)", which is not marked
with 'atnight', when "git show 88d50e7" gives correct author date of
"Sat Jan 9 00:18:07 2010 +0530".

'git am --abort' is around for quite a long time now, and users should
normally not poke around inside the .git directory, yet the
documentation of 'git am' still recommends the following:
... if you decide to start over from scratch,
run `rm -f -r .git/rebase-apply` ...
Suggest 'git am --abort' instead.
It's not quite the same as the original, because 'git am --abort' will
restore the original branch, while simply removing '.git/rebase-apply'
won't, but that's rather a thinko in the original wording, because
that won't actually "start over _from scratch_".

Traditional "opportunistic index update" done by read-only "diff" and
"status" was about updating cached lstat(2) information in the index for
the next round. We missed another obvious optimization opportunity: when
there are racily clean entries that will cease to be racily clean by
updating $GIT_INDEX_FILE. Detect that case and write $GIT_INDEX_FILE out
to give it a newer timestamp.
Noticed by Lasse Makholm by stracing "git status" in a fresh checkout and
counting the number of open(2) calls.

When we had to refresh the index internally before running diff or status,
we opportunistically updated the $GIT_INDEX_FILE so that later invocation
of git can use the lstat(2) we already did in this invocation.

If gitk is not available in the PATH, bisect ends up
exiting with the shell's 127 error code, confusing the git
wrapper into thinking that bisect is not a git command.
We already fallback to git-log if there doesn't seem to be a
graphical display available. We should do the same if gitk
is not available in our PATH at all. This not only fixes the
ugly error message, but is a much more sensible default than
failing to show the user anything.
