Re: [PATCH] git wrapper: add --git-path=<path> and --bare options

With this, you can say

	git --bare repack -a -d

inside a bare repository, and it will actually work. While at it,
also move the --version, --help and --exec-path options to the
handle_options() function.

Thanks.  Took a liberty cleaning up a few stuff, but will have
both alias-p and this patch in "next" shortly.
