Earlier round showed the commit log header and "diff --combined"
header even for paths that had no interesting hunk under --cc
flag. Move the header display logic around to squelch them.
With this, a merge that does not have any interesting merges
will not be shown with --cc option, unless -m is used at the
same time.

Santi Bejar points out that a hunk that changes from all the
same common parents except one is uninteresting. The earlier
round marked changes from only one parent uninteresting, but
this also marks hunks that have the same change from all but one
parent uninteresting, which is a natural extension of the
original idea to Octopus merges.

Remove extra whitespace between the change indicators and the
body text. That is more in line with the uncombined unified
diff output (pointed out by Santi Bejar).
When showing --cc, say so instead of saying just --combined.

Building on the previous '-c' (combined) option, '--cc' option
squelches the output further by omitting hunks that consist of
difference with solely one parent.

A new option '-c' to diff-tree changes the way a merge commit is
displayed when generating a patch output. It shows a "combined
diff" (hence the option letter 'c'), which looks like this:
$ git-diff-tree --pretty -c -p fec9ebf1 | head -n 18
diff-tree fec9ebf... (from parents)
Merge: 0620db3... 8a263ae...

- static void describe(struct commit *cmit, int last_one)
++ static void describe(char *arg, int last_one)
{
+ unsigned char sha1[20];
+ struct commit *cmit;
There are a few things to note about this feature:
- The '-c' option implies '-p'. It also implies '-m' halfway
in the sense that "interesting" merges are shown, but not all
merges.
- When a blob matches one of the parents, we do not show a diff
for that path at all. For a merge commit, this option shows
paths with real file-level merge (aka "interesting things").
- As a concequence of the above, an "uninteresting" merge is
not shown at all. You can use '-m' in addition to '-c' to
show the commit log for such a merge, but there will be no
combined diff output.
- Unlike "gitk", the output is monochrome.
A '-' character in the nth column means the line is from the nth
parent and does not appear in the merge result (i.e. removed
from that parent's version).
A '+' character in the nth column means the line appears in the
merge result, and the nth parent does not have that line
(i.e. added by the merge itself or inherited from another
parent).
The above example output shows that the function signature was
changed from either parents (hence two "-" lines and a "++"
line), and "unsigned char sha1[20]", prefixed by a " +", was
inherited from the first parent.
The code as sent to the list was buggy in few corner cases,
which I have fixed since then.
It does not bother to keep track of and show the line numbers
from parent commits, which it probably should.

The files with conflicts need to be hand resolved, and it is a
good discipline for the committer to explain which branch was
taken and why. Pre-fill the merge message template with the

If you pass it a filename without the "--" marker to separate it from
revision information and flags, we now require that the file in question
actually exists. This makes mis-typed revision information not be silently
just considered a strange filename.
With the "--" marker, you can continue to pass in filenames that do not
actually exists - useful for querying what happened to a file that you
no longer have in the repository.
[ All scripts should use the "--" format regardless, to make things
unambiguous. So this change should not affect any existing tools ]

sysadmin disservice). It may be legal to configure your sshd to
spawn named program without involving shell at all, and if your
sysadmin does so and you have your git programs under your home
directory, you would need something like this, but then I suspect
you would need such workaround everywhere, not just git. But we
have these options we can use to work around the issue, so there
is no strong reason not to reject this patch, either. ]

This is the update hook we use in all our git-repos.
It has some improvements over the original version, namely:
* Don't send every commit since dawn of time when adding a new tag.
* When updating an annotated tag, just send the diffs since the last tag.
* Add diffstat output for 'normal' commits (top) and annotated tags (bottom).
* Block un-annotated tags in shared repos.
I'm a bit uncertain about that last one, but it demonstrates how to
disallow updates of a ref which we use, so I kept it.
Note that git-describe is needed for the "changes since last annotated tag"
thing to work.

It is a common mistake to leave an unsed `origin` branch behind
if a shared public repository was created by first cloning from

the developer repository uselessly.

The current Documentation/tutorial.txt concentrates on the lower-level
git interfaces. So it's useful to people developing alternative

We forgot to make sure that there is no more than one pattern
parameter. Also when looking for files in a directory called
'--others', it passed that path limiter without preceding the
end-of-options marker '--' to underlying git-ls-files, which
misunderstood it as one of its options instead.
$ git grep --others -e Meta/Make Meta
$ git grep -o -e Meta/Make Meta
$ git grep -o Meta/Make Meta
look for a string "Meta/Make" from untracked files in Meta/
directory.
$ git grep Meta/Make --others
looks for the same string from tracked files in ./--others
directory.
On the other hand,
$ git grep -e Meta/Make --others
does not have a freestanding pattern, so everybody is parameter
and there is no path specifier. It looks for the string in all
the untracked files without any path limiter.

When overriding DT_* macro detection with NO_D_TYPE_IN_DIRENT (recent
Cygwin build problem, which hopefully is already fixed in their CVS
snapshot version), we define DTYPE() macro to return just "we do not
know", but still needed to use DT_* macro to avoid ifdef in the code
we use them. If the platform defines DT_* macro but with unusable
d_type, this would have resulted in us redefining these preprocessor
symbols.
Admittedly, that would be just a couple of compilation warnings, and
on Cygwin at least this particular problem is transitory (the problem
is already fixed in their CVS snapshot version), so this is a low
priority fix.

This test depended on "sleep 1" to be enough to dirty the index
entry for a symlink. Alex noticed that on his Cygwin installation
"sleep 1" was sometimes not enough, and after further discussion with
Christopher Faylor, it was brought up that on FAT filesystem timestamp
granularity is 2 seconds so sleeping 1 second is not enough.
For now this patch takes an easy workaround of sleeping for 3 seconds.
Very strictly speaking, POSIX requires lstat to fill only S_IFMT part
of st_mode and st_size for symlinks, and depending on timestamp might
be considered a bug, but we depend on that anyway, so it is better to
test that.

The d_ino field is only used for performance reasons in
fsck-objects. On a typical filesystem, i-number tends to have a
strong correlation with where the actual bits sit on the disk
platter, and we sort the entries to allow us scan things that
ought to be close together together.
If the platform lacks support for it, it is not a big deal.
Just do not use d_ino for sorting, and scan them unsorted.
