[RFC PATCH] stash: accept options also when subcommand 'save' is omitted

[Matthieu Moy <Matthieu.Moy@imag.fr>]

This allows in particular 'git stash --keep-index' which is shorter than
'git stash save --keep-index', and not ambiguous.

Does this sound right?

I'm so used to 'git stash' (without saying 'save') that I keep typing
'git stash --keep-index', and get a usage string as an error message.
