b73cebf437 Fix nasty approxidate bug
Stupid me.

If approxidate ends up with a month that is ahead of the current month, it
decrements the year to last year.

Which is correct, and means that "last december" does the right thing.

HOWEVER. It should only do so if the year is the same as the current year.

Without this fix, "5 days ago" ends up being in 2004, because it first
decrements five days, getting us to December 2005 (correct), but then it
also ends up decrementing the year once more to turn that December into
"last year" (incorrect, since it already _was_ last year).

Duh. Pass me a donut.

0a15217184 AIX compile fix for repo-config.c
AIX 5 has a /usr/include/regex.h containing this code:

 #ifdef  _NO_PROTO
 extern  char    *regex();
 extern  char    *regcmp();
 #else /* _NO_PROTO */
 extern  char    *regex(const char *, const char *, ...);
 extern  char    *regcmp(const char *, ...);
 #endif  /* _NO_PROTO */

This means that repo-config.c is trying to redefine the `regex' symbol.
Here is a simple patch that just uses `regexp' as the symbol name instead.

908e5310b9 Add a "git-describe" command
It shows you the most recent tag that is reachable from a particular
commit is.

Maybe this is something that "git-name-rev" should be taught to do,
instead of having a separate command for it. Regardless, I find it useful.

What it does is to take any random commit, and "name" it by looking up the
most recent commit that is tagged and reachable from that commit. If the
match is exact, it will just print out that ref-name directly. Otherwise
it will print out the ref-name, followed by the 8-character "short SHA".

IOW, with something like Junios current tree, I get:

	[torvalds@g5 git]$ git-describe parent
	refs/tags/v1.0.4-g2414721b

ie the current head of my "parent" branch (ie Junio) is based on v1.0.4,
but since it has a few commits on top of that, it has added the git hash
of the thing to the end: "-g" + 8-char shorthand for the commit
2414721b19.

Doing a "git-describe" on a tag-name will just show the full tag path:

	[torvalds@g5 git]$ git-describe v1.0.4
	refs/tags/v1.0.4

unless there are _other_ tags pointing to that commit, in which case it
will just choose one at random.

This is useful for two things:

 - automatic version naming in Makefiles, for example. We could use it in
   git itself: when doing "git --version", we could use this to give a
   much more useful description of exactly what version was installed.

 - for any random commit (say, you use "gitk <pathname>" or
   "git-whatchanged" to look at what has changed in some file), you can
   figure out what the last version of the repo was. Ie, say I find a bug
   in commit 39ca371c45b04cd50d0974030ae051906fc516b6, I just do:

	[torvalds@g5 linux]$ git-describe 39ca371c45b04cd50d0974030ae051906fc516b6
	refs/tags/v2.6.14-rc4-g39ca371c

   and I now know that it was _not_ in v2.6.14-rc4, but was presumably in
   v2.6.14-rc5.

The latter is useful when you want to see what "version timeframe" a
commit happened in.

975b31dc6e Handle symlinks graciously
This patch converts a stat() to an lstat() call, thereby fixing the case
when the date of a symlink was not the same as the one recorded in the
index. The included test case demonstrates this.

This is for the case that the symlink points to a non-existing file. If
the file exists, worse things than just an error message happen.

7d6fb370bc short circuit out of a few places where we would allocate zero bytes
dietlibc versions of malloc, calloc and realloc all return NULL if
they're told to allocate 0 bytes, causes the x* wrappers to die().

There are several more places where these calls could end up asking
for 0 bytes, too...

Maybe simply not die()-ing in the x* wrappers if 0/NULL is returned
when the requested size is zero is a safer and easier way to go.

457f06d68e Introduce core.sharedrepository
If the config variable 'core.sharedrepository' is set, the directories

	$GIT_DIR/objects/
	$GIT_DIR/objects/??
	$GIT_DIR/objects/pack
	$GIT_DIR/refs
	$GIT_DIR/refs/heads
	$GIT_DIR/refs/heads/tags

are set group writable (and g+s, since the git group may be not the primary
group of all users).

Since all files are written as lock files first, and then moved to
their destination, they do not have to be group writable.  Indeed, if
this leads to problems you found a bug.

Note that -- as in my first attempt -- the config variable is set in the
function which checks the repository format. If this were done in
git_default_config instead, a lot of programs would need to be modified
to call git_config(git_default_config) first.

[jc: git variables should be in environment.c unless there is a
 compelling reason to do otherwise.]

a69dd585fc ls-tree: chomp leading directories when run from a subdirectory
When run from a subdirectory, even though we filtered the output
based on where we were using pathspec, we wrote out the
repository relative paths, not subtree relative paths.  This
changes things so that it shows only the current subdirectory
relative paths.

For example, in Documentation subdirectory of git itself, this
used to be the case:

    $ git-ls-tree --name-only HEAD | grep how
    Documentation/git-show-branch.txt
    Documentation/git-show-index.txt
    Documentation/howto-index.sh
    Documentation/howto

But now it does this instead:

    $ git-ls-tree --name-only HEAD | grep how
    git-show-branch.txt
    git-show-index.txt
    howto-index.sh
    howto

There are two things to keep in mind.

1. This shows nothing.

   $ git-ls-tree --name-only HEAD ../ppc/

   This is to make things consistent with ls-files, which
   refuses relative path that goes uplevel.

2. These show things in full repository relative paths.  In this
   case, paths outside the current subdirectory are also shown.

   $ git-ls-tree --name-only --full-name HEAD | grep how
   Documentation/git-show-branch.txt
   Documentation/git-show-index.txt
   Documentation/howto-index.sh
   Documentation/howto

   $ git-ls-tree --name-only --full-name HEAD ../ppc/
   ppc/sha1.c
   ppc/sha1.h
   ppc/sha1ppc.S

The flag --full-name gives the same behaviour as 1.0, so it
ought to be the default if we really care about the backward
compatibility, but in practice no Porcelain runs ls-tree from a
subdirectory yet, and without --full-name is more human
friendly, so hopefully the default being not --full-name would
be acceptable.

104f3e03c0 checkout: sometimes work from a subdirectory.
git-checkout does two very different things, and what they
should do when run from subdirectory are quite different.

It does not make any sense to run the one that switches the
current head from anywhere other than the toplevel:

	git-checkout [-f] <branch>
        git-checkout [-b <branch>] <committish>

We could of course chdir to top and do the whole-tree checkout
in git-checkout, but the point is the operation does not make
sense on a partial tree.  The whole tree is checked out.

The other form is to update the index file and working tree file
selectively:

	git-checkout <treeish> <file>... ;# out of tree to index and file
        git-checkout -- <file>...	 ;# out of index to file

This form _does_ make sense to run from subdirectory; and I
myself often wish we supported this.

So here is a patch to do both.
