e5c2909782 add -i: add extra options at the right place in "diff" command line
Appending "--diff-algorithm=histogram" at the end of canned command
line for various modes of "diff" is correct for most of them but not
for "stash" that has a non-option already wired in, like so:

	'stash' => {
		DIFF => 'diff-index -p HEAD',

Appending an extra option after non-option may happen to work due to
overly lax command line parser, but that is not something we should
rely on.  Instead, splice in the extra argument immediately after the
command name (i.e. 'diff-index', 'diff-files', etc.).

55cfde251b remote: remove dead code in read_branches_file()
The first line of the function checks that the remote-name contains a
slash ('/'), and sets the "slash" variable accordingly.  The only caller
of read_branches_file() is remote_get_1(); the calling codepath is
guarded by valid_remote_nick(), which checks that the remote does not
contain a slash.  Therefore, the "slash" variable can never be set:
remove the dead code that assumes otherwise.

9b9439afd8 t/t5505-remote: modernize style
Modernize the style of all tests throughout the file:

 - Remove spurious blank lines.

 - Indent the test body.

 - Make sure that all lines end with &&, to make it easier to spot
   breaks in the chain.

 - When executing something in a subshell, put the parenthesis on
   separate lines and indent the body.  Also make sure that the
   first statement in the subshell is a 'cd'.

 - When redirecting input or output, do not use SP between
   redirection operator and the target filename.

 - Use the <<-\EOF and <<-EOF forms of heredoc, not <<EOF, when the
   command is indented and the heredoc text itself does not have to
   have a leading tab.

34a25d4c90 Documentation: Update the NFS remote examples to use the staging repo
linux-nfs.org seems to have restructured their repository layout since
8391c60 (git-remote.txt: fix example url, 2007-11-02), and Bruce's
repo is now at git://git.linux-nfs.org/projects/bfields/linux.git.
Bruce also has a more richer internal branch structure (master,
everything, for-3.1, ...), so updating the existing example to use his
current repo may be confusing.

To simplify, I've replaced the NFS repo with Greg's staging repo.
I've also updated the output of the surrounding commands to match the
output of a current run through.

There may be times when using one of your local repositories as a

5bdc47eb55 lib-httpd/apache.conf: check version only after mod_version loads
Commit 0442743 introduced an <IfVersion> directive near the
top of the apache config file. However, at that point we
have not yet checked for and loaded the mod_version module.
This means that the directive will behave oddly if
mod_version is dynamically loaded, failing to match when it
should.

We can fix this by moving the whole block below the
LoadModule directive for mod_version.

aff2e7c067 t6003: add --author-date-order test
Tweak the --topo/date-order test vector a bit and mark the author
dates of two commits (a2 and a3) earlier than their own committer
dates, making them much older than other commits that are made on
parallel branches to simulate the case where a long running topic
was rebased recently.

They will show up as recent in the --date-order output due to their
timestamps, but they appear a lot later in the --author-date-order
output, even though their committer timestamp says otherwise.

841dc6935e topology tests: teach a helper to take abbreviated timestamps
The on_committer_date helper in t/lib-t6000 is used in t6002 and
t6003 with timestamps on a single day within a single minute
(i.e. 1971-08-16 00:00) and the tests repeat this over and over.

The actual value of the timestamp, however, does not matter very
much; only their relative ordering does.

Introduce another helper to expand only the suffix of the timestamp
to a full timestamp to make the lines shorter, and use it in this
helper.  Also, because all the commits in the test are made with
specific GIT_COMMITTER_DATE, stop unsetting it at the end of the
helper.

We'll be specifying the author timestamp to these test commits in a
later patch, which will be helped with this change.

Also remove a test that was commented-out from t6003; it used to
test a commit with the same parent listed twice, which was allowed
by mistake but was fixed long time ago.

266f1fdfa9 transport-helper: be quiet on read errors from helpers
Prior to commit 81d340d4, we did not print any error message
if a remote transport helper died unexpectedly. If a helper
did not print any error message (e.g., because it crashed),
the user could be left confused. That commit tried to
rectify the situation by printing a note that the helper
exited unexpectedly.

However, this makes a much more common case worse: when a
helper does die with a useful message, we print the extra
"Reading from 'git-remote-foo failed" message. This can also
end up confusing users, as they may not even know what
remote helpers are (e.g., the fact that http support comes
through git-remote-https is purely an implementation detail
that most users do not know or care about).

Since we do not have a good way of knowing whether the
helper printed a useful error, and since the common failure
mode is for it to do so, let's default to remaining quiet.
Debuggers can dig further by setting GIT_TRANSPORT_HELPER_DEBUG.

forgot that find_name_traditional() can return NULL as a way of saying
"I couldn't find a name".

That NULL unfortunately gets passed into xstrdup() next, resulting in
a segfault.  Use null_strdup() so as to safely propagate the null,
which will let us emit the correct error message.

b4dc085a8d pull: merge into unborn by fast-forwarding from empty tree
The logic for pulling into an unborn branch was originally
designed to be used on a newly-initialized repository
(d09e79c, git-pull: allow pulling into an empty repository,
2006-11-16).  It thus did not initially deal with
uncommitted changes in the unborn branch.  The case of an
_unstaged_ untracked file was fixed by 4b3ffe5 (pull: do not
clobber untracked files on initial pull, 2011-03-25).
However, it still clobbered existing staged files, both when
the file exists in the merged commit (it will be
overwritten), and when it does not (it will be deleted).

We fix this by doing a two-way merge, where the "current"
side of the merge is an empty tree, and the "target" side is
HEAD (already updated to FETCH_HEAD at this point).  This
amounts to claiming that all work in the index was done vs.
an empty tree, and thus all content of the index is
precious.

Note that this use of read-tree just gives us protection
against overwriting index and working tree changes. It will
not actually result in a 3-way merge conflict in the index.
This is fine, as this is a rare situation, and the conflict
would not be interesting anyway (it must, by definition, be
an add/add conflict with the whole content conflicting). And
it makes it simpler for the user to recover, as they have no
HEAD to "git reset" back to.

9f48f2bd9a pull: update unborn branch tip after index
When commit d09e79c taught git to pull into an unborn
branch, it first updated the unborn branch to point at the
pulled commit, and then used read-tree to update the index
and working tree. That ordering made sense, since any
failure of the latter step would be due to filesystem
errors, and one could then recover with "git reset --hard".

Later, commit 4b3ffe5 added extra safety for existing files
in the working tree by asking read-tree to bail out when it
would overwrite such a file. This error mode is much less
"your pull failed due to random errors" and more like "we
reject this pull because it would lose data". In that case,
it makes sense not to update the HEAD ref, just as a regular
rejected merge would do.

This patch reverses the order of the update-ref and
read-tree calls, so that we do not touch the HEAD ref at all if a
merge is rejected. This also means that we would not update
HEAD in case of a transient filesystem error, but those are
presumably less rare (and one can still recover by repeating
the pull, or by accessing FETCH_HEAD directly).

While we're reorganizing the code, we can drop the "exit 1"
from the end of our command chain. We exit immediately
either way, and just calling exit without an argument will
use the exit code from the last command.
