[PATCH] git-stash: Display help message if git-stash is run with wrong sub-commands

["Kevin Leung" <kevinlsk@gmail.com>]

The current git-stash behaviour is very error prone to typos. For example,
if you typed "git-stash llist", git-stash would think that you wanted to
save to a stash named "llist", but in fact, you meant "git-stash list".
