The git suite may not be in PATH (and thus programs such as
git-send-pack could not exec git-rev-list).  Thus there is a need for
logic that will locate these programs.  Modifying PATH is not
desirable as it result in behavior differing from the user's
intentions, as we may end up prepending "/usr/bin" to PATH.

- git C programs will use exec*_git_cmd() APIs to exec sub-commands.
- exec*_git_cmd() will execute a git program by searching for it in
  the following directories:
	1. --exec-path (as used by "git")
	2. The GIT_EXEC_PATH environment variable.
	3. $(gitexecdir) as set in Makefile (default value $(bindir)).
- git wrapper will modify PATH as before to enable shell scripts to
  invoke "git-foo" commands.

Ideally, shell scripts should use the git wrapper to become independent
of PATH, and then modifying PATH will not be necessary.

We rejected multi-base merge situations even though we used the
same underlying multi-base git-read-tree as the resolve strategy
uses.  This was unneeded and did not add much to ensure the
merge to be truly trivial, so remove this restriction and be
more similar to what resolve does.

Also when the merge did not trivially resolve, we rejected
without stating that octopus strategy does not handle the
situation.

This lets showbranch.default multivalued configuration item to
be used as the default set of parameters to git-show-branch when
none is given on the command line.

I keep many topic branches (e.g. zzz/pack, net/misc) and
branches used only as a reference under subdirectories
(e.g. hold/{html,man,todo} track the same from git.git, but
clutters the show-branch output when shown along with the main
development; ko/master tracks what I have pushed out already and
refetched from the kernel.org server), and often run:

	$ git show-branch ko/master heads/*

to view only the ko/master head and branches I keep immediately
under $GIT_DIR/refs/heads.  With this change, I can have this in
my $GIT_DIR/config file:

	[showbranch]
		default = ko/master
		default = heads/*

and say

	$ git show-branch

When both howto-index.sh and howto/make-dist.txt exist under
Documentation/ directory, dir_exists() mistakenly checked it
without the trailing slash to see if there was something under
Documentation/howto directory, and did not realize there was,
because '-' sorts earlier than '/' and cache_name_pos() finds
howto-index.sh, which is not under howto/ directory.  This
caused --others --directory to show it which was incorrect.

Check the directory name with the trailing slash, because having
an entry that has such as a prefix is what we are looking for.

Darrin Thompson notes that git-ls-files -o reports all the unknown
files it finds in a work area.  Subversion and probably other systems
"simply ignore all the files and directories inside an unknown

I added things to ls-remote so that Cogito can auto-follow tags
easily and correctly a while ago, but git-fetch did not use the
facility.  Recently added git-describe command relies on
repository keeping up-to-date set of tags, which made it much
more attractive to automatically follow tags, so we do that as
well.

ISO C99 (and GCC 3.x or later) lets you write a flexible array
at the end of a structure, like this:

	struct frotz {
		int xyzzy;
		char nitfol[]; /* more */
	};

GCC 2.95 and 2.96 let you to do this with "char nitfol[0]";
unfortunately this is not allowed by ISO C90.

This declares such construct like this:

	struct frotz {
		int xyzzy;
		char nitfol[FLEX_ARRAY]; /* more */
	};

and git-compat-util.h defines FLEX_ARRAY to 0 for gcc 2.95 and
empty for others.

If you are using a C90 C compiler, you should be able
to override this with CFLAGS=-DFLEX_ARRAY=1 from the
command line of "make".

I think it is probably a bug that "git non_existent_command"
returns its error message to stdout without an error, where
"git-non_existent_command" behaves differently and does return an
error.

Older versions of git did not implement "git describe"  and
GIT-VERSION-GEN produces an empty version string if run on
a system with such a git installed.  The consequence
is that "make rpm" fails.

This patch fixes GIT-VERSION-GEN so that it works in the
absence of a working "git describe"
