A typical setup under Windows is to set core.eol to CRLF, and text
files are marked as "text" in .gitattributes, or core.autocrlf is
set to true.
After 4d4813a5 "git blame" no longer works as expected for such a
set-up. Every line is annotated as "Not Committed Yet", even though
the working directory is clean. This is because the commit removed
the conversion in blame.c for all files, with or without CRLF in the
repo.
Having files with CRLF in the repo and core.autocrlf=input is a
temporary situation, and the files, if committed as is, will be
normalized in the repo, which _will_ be a notable change. Blaming
them with "Not Committed Yet" is the right result. Revert commit
4d4813a5 which was a misguided attempt to "solve" a non-problem.
Add two test cases in t8003 to verify the correct CRLF conversion.

We had this in "git merge" manual for eternity:
'git merge' <msg> HEAD <commit>...
[This] syntax (<msg> `HEAD` <commit>...) is supported for
historical reasons. Do not use it from the command line or in
new scripts. It is the same as `git merge -m <msg> <commit>...`.
With the update to "git merge" to make it understand what is
recorded in FETCH_HEAD directly, including Octopus merge cases, we
now can rewrite the use of this syntax in "git pull" with a simple
"git merge FETCH_HEAD".
Also there are quite a few fallouts in the test scripts, and it
turns out that "git cvsimport" also uses this old syntax to record
a merge.
Judging from this result, I would not be surprised if dropping the
support of the old syntax broke scripts people have written and been
relying on for the past ten years. But at least we can start the
deprecation process by throwing a warning message when the syntax is
used.
With luck, we might be able to drop the support in a few years.

The collect_parents() function now is responsible for
1. parsing the commits given on the command line into a list of
commits to be merged;
2. filtering these parents into independent ones; and
3. optionally calling fmt_merge_msg() via prepare_merge_message()
to prepare an auto-generated merge log message, using fake
contents that FETCH_HEAD would have had if these commits were
fetched from the current repository with "git pull . $args..."
Make "git merge FETCH_HEAD" to be the same as the traditional
git merge "$(git fmt-merge-msg <.git/FETCH_HEAD)" $commits
invocation of the command in "git pull", where $commits are the ones
that appear in FETCH_HEAD that are not marked as not-for-merge, by
making it do a bit more, specifically:
- noticing "FETCH_HEAD" is the only "commit" on the command line
and picking the commits that are not marked as not-for-merge as
the list of commits to be merged (substitute for step #1 above);
- letting the resulting list fed to step #2 above;
- doing the step #3 above, using the contents of the FETCH_HEAD
instead of fake contents crafted from the list of commits parsed
in the step #1 above.
Note that this changes the semantics. "git merge FETCH_HEAD" has
always behaved as if the first commit in the FETCH_HEAD file were
directly specified on the command line, creating a two-way merge
whose auto-generated merge log said "merge commit xyz". With this
change, if the previous fetch was to grab multiple branches (e.g.
"git fetch $there topic-a topic-b"), the new world order is to
create an octopus, behaving as if "git pull $there topic-a topic-b"
were run. This is a deliberate change to make that happen, and
can be seen in the changes to t3033 tests.

On some systems (like OS X), if sed encounters input without
a trailing newline, it will silently add it. As a result,
"git filter-branch" on such systems may silently rewrite
commit messages that omit a trailing newline. Even though
this is not something we generate ourselves with "git
commit", it's better for filter-branch to preserve the
original data as closely as possible.
We're using sed here only to strip the header fields from
the commit object. We can accomplish the same thing with a
shell loop. Since shell "read" calls are slow (usually one
syscall per byte), we use "cat" once we've skipped past the
header. Depending on the size of your commit messages, this
is probably faster (you pay the cost to fork, but then read
the data in saner-sized chunks). This idea is shamelessly
stolen from Junio.

When rebase--interactive processes a task, it removes the item from
the todo list and appends it to another list of executed tasks. If a
pick (this includes squash and fixup) fails before the index has
recorded the changes, take the corresponding item and put it on the todo
list again. Otherwise, the changes introduced by the scheduled commit
would be lost.
That kind of decision is possible since the cherry-pick command
signals why it failed to apply the changes of the given commit. Either
the changes are recorded in the index using a conflict (return value 1)
and rebase does not continue until they are resolved or the changes
are not recorded in the index (return value neither 0 nor 1) and
rebase has to try again with the same task.
Add a test cases for regression testing to the "rebase-interactive"

The git_connect function has code to handle plink and tortoiseplink
specially, as they require different command line arguments from
OpenSSH (-P instead of -p for ports; tortoiseplink additionally requires
-batch). However, the match was done by checking for "plink" anywhere
in the string, which led to a GIT_SSH value containing "uplink" being
treated as an invocation of putty's plink.
Improve the check by looking for "plink" or "tortoiseplink" (or those
names suffixed with ".exe") only in the final component of the path.
This has the downside that a program such as "plink-0.63" would no
longer be recognized, but the increased robustness is likely worth it.
Add tests to cover these cases to avoid regressions.

One of the tests in t5601 used single quotes to delimit an argument
containing spaces. However, this caused test_expect_success to be
passed three arguments instead of two, which in turn caused the test
name to be treated as a prerequisite instead of a test name. As there
was no prerequisite called "bracketed hostnames are still ssh", the test
was always skipped.
Because this test was always skipped, the fact that it passed the
arguments in the wrong order was obscured. Use double quotes inside the
test and reorder the arguments so that the test runs and properly
reflects the arguments that are passed to ssh.

To support this functionality while branch detection is

This patch does two things to fix improve file location

1. Enable usage of "p4 where" when Perforce branches exist
in the git repository, even when client specification is
used. This makes use of the already existing function
p4Where.

If you have staged contents in your index and run "stash
apply", we may hit a conflict and put new entries into the
index. Recovering to your original state is difficult at
that point, because tools like "git reset --keep" will blow
away anything staged. We can make this safer by refusing to
apply when there are staged changes.
It's possible we could provide better tooling here, as "git
stash apply" should be writing only conflicts to the index
(so we know that any stage-0 entries are potentially
precious). But it is the odd duck; most "mergy" commands
will update the index for cleanly merged entries, and it is
not worth updating our tooling to support this use case
which is unlikely to be of interest (besides which, we would
still need to block a dirty index for "stash apply --index",
since that case _would_ be ambiguous).
