Subject: stash: recognize "--help" for subcommands

If you run "git stash --help", you get the help for stash
(this magic is done by the git wrapper itself). But if you
run "git stash drop --help", you get an error. We
cannot show help specific to "stash drop", of course, but we
can at least give the user the normal stash manpage.
