When using rebase --interactive where one of the lines is marked as
'edit' this is the resulting output:
Stopped at ec3b9c4... stuffYou can amend the commit now, with
git commit --amend
Once you are satisfied with your changes, run
git rebase --continue
A newline character is missing at the end of the "Stopped at ..." line and
before the "You can amend ..." line. This patch fixes the malformed output by
adding the missing newline character to the end of the "Stopped at ..." line.

"Cc:" on the trailer part does not have to conform to RFC strictly,

A caller of tempfile API that uses stdio interface to write to
files may ignore errors while writing, which is detected when
tempfile is closed (with a call to ferror()). By that time, the
original errno that may have told us what went wrong is likely to
be long gone and was overwritten by an irrelevant value.
close_tempfile() now resets errno to EIO to make errno at least
predictable.

A "gc.log" file left by a backgrounded "gc --auto" disables further

"git upload-pack", which is a counter-part of "git fetch", did not
report a request for a ref that was not advertised as invalid.
This is generally not a problem (because "git fetch" will stop
before making such a request), but is the right thing to do.

"git diff --quiet" relies on the size field in diff_filespec to be
correctly populated, but diff_populate_filespec() helper function
made an incorrect short-cut when asked only to populate the size
field for paths that need to go through convert_to_git() (e.g. CRLF
conversion).
* jc/diff-populate-filespec-size-only-fix:

"Dumb http" transport used to misparse a nonsense http-alternates
response, which has been fixed.

"git difftool --dir-diff" used to die a controlled death giving a
"fatal" message when encountering a locally modified symbolic link,
but it started segfaulting since v2.12. This has been fixed.

t7800: cleanup cruft left behind by tests
t7800: remove whitespace before redirect
Change the documentation for push.tracking=* to re-include a mention
of what "tracking" does.
The "tracking" option was renamed to "upstream" back in
53c4031 ("push.default: Rename 'tracking' to 'upstream'", 2011-02-16),
this section was then subsequently rewritten in 87a70e4 ("config doc:
rewrite push.default section", 2013-06-19) to remove any mention of
"tracking".
Maybe we should just warn or die nowadays if this option is in the
config, but I had some old config of mine use this option, I'd
forgotten that it was a synonym, and nothing in git's documentation
mentioned that.
That's bad, either we shouldn't support it at all, or we should
document what it does. This patch does the latter.

The hook was added in a86ed83cce (Merge branch 'tr/notes-display' -
2010-03-24), which updated githooks.txt but not git-commit.txt.
git-commit.txt was later updated in e858af6d50 (commit: document a
couple of options - 2012-06-08). Since this commit focused on command
line options, this section was probably forgotten.

'git {log,diff,...} -S<...> --pickaxe-regex' can segfault as a result
of out-of-bounds memory reads.
diffcore-pickaxe.c:contains() looks for all matches of the given regex
in a buffer in a loop, advancing the buffer pointer to the end of the
last match in each iteration. When we switched to REG_STARTEND in
b7d36ffca (regex: use regexec_buf(), 2016-09-21), we started passing
the size of that buffer to the regexp engine, too. Unfortunately,
this buffer size is never updated on subsequent iterations, and as the
buffer pointer advances on each iteration, this "bufptr+bufsize"
points past the end of the buffer. This results in segmentation
fault, if that memory can't be accessed. In case of 'git log' it can
also result in erroneously listed commits, if the memory past the end
of buffer is accessible and happens to contain data matching the
regex.
Reduce the buffer size on each iteration as the buffer pointer is
advanced, thus maintaining the correct end of buffer location.
Furthermore, make sure that the buffer pointer is not dereferenced in
the control flow statements when we already reached the end of the
buffer.
The new test is flaky, I've never seen it fail on my Linux box even
without the fix, but this is expected according to db5dfa3 (regex:
-G<pattern> feeds a non NUL-terminated string to regexec() and fails,
2016-09-21). However, it did fail on Travis CI with the first (and
incomplete) version of the fix, and based on that commit message I
would expect the new test without the fix to fail most of the time on
Windows.

Callers of the run-command API may mark a child as
"clean_on_exit"; it gets added to a list and killed when the
main process dies. Since commit 46df6906f
(execv_dashed_external: wait for child on signal death,
2017-01-06), we respect an extra "wait_after_clean" flag,
which we expect to find in the child_process struct.
When Git is built with NO_PTHREADS, we start "struct
async" processes by forking rather than spawning a thread.
The resulting processes get added to the cleanup list but
they don't have a child_process struct, and the cleanup
function ends up dereferencing NULL.
We should notice this case and assume that the processes do
not need to be waited for (i.e., the same behavior they had
before 46df6906f).

The string after_subject is added to a strbuf by pp_title_line() if
it's not NULL. Adding an empty string has the same effect as not
adding anything, but the latter is easier, so don't bother changing
the context member from NULL to "".
