Re: [PATCH] Makes 'git-stash show' stay quiet when there are no stashes.

Currently when there are no stashes, 'git stash show' basically aborts with an
error message from rev-parse: "fatal: Needed a single revision", which can be
confusing. This patch makes git-stash keep quiet and exit gracefully in that
case.

I agree "git stash show" should not give cryptic error message, but I
think you should do this only when the user did not explicitly say which
stash to show (that is, we should still give error message if the user
said "git stash show garbage").
