As Matthias Kestenholz noted, the flag does not quite mean
"needs prefix" -- it is more like "run setup_git_directory()
before running this command", so rename it to avoid future
confusion.

While we are at it, rewrite the definition of options to make it
obvious that we are talking about flag bits by using standard (1<<n)
notation.

This cleans up the build procedure for built-in commands by:

 - generating mostly redundant definition of BUILT_INS from
   BUILTIN_OBJS in the Makefile,
 - renaming a few files to make the above possible, and
 - sorting the built-in command table in git.c.

It might be a good idea to binary search (or perfect hash) the built-in
command table, but that can be done later when somebody feels like.

The cmd_usage() routine was causing warning messages due to a NULL
format parameter being passed in three out of four calls. This is a
problem if you want to compile with -Werror. A simple solution is to
simply remove the GNU __attribute__ format pragma from the cmd_usage()
declaration in the header file. The function interface was somewhat
muddled anyway, so re-write the code to finesse the problem.

[jc: this incidentally revealed that t9100 test assumed that the output
 from "git help" to be fixed in stone, but this patch lower-cases
 "Usage" to "usage".  Update the test not to rely on "git help" output.]

This moves the built-in "always-use-pager" logic for log family
to the command dispatch table of git wrapper.  This makes it
easier to change the default use of pager, and has an added
benefit that we fork and exec the pager early before packs are
mmapped.

This actually removes the objects to be pruned, unless you specify "-n"
(at which point it will just tell you which files it would prune).

This doesn't do the pack-file pruning that the shell-script used to do,
but if somebody really wants to, they could add it easily enough. I wonder
how useful it is, though, considering that "git repack -a -d" is just a
lot more efficient and generates a better end result.

git.c:main() relies on the value of errno being set by the last attempt to
execute the command. However, if something goes awry in handle_alias(),
that assumption is wrong. So restore errno before returning from

This disables alias "foo" from being used for git-foo, and when
we do use alias we check the built-in and then existing command
names first and then alias as the fallback.  This avoids the
problem of common commands used in scripts getting clobbered by
user specific aliases.
