bash: update 'git stash' completion

This update adds 'git stash (apply|pop) --quiet' and all options known
to 'git stash save', and handles the DWIMery from 3c2eb80f (stash:
simplify defaulting to "save" and reject unknown options, 2009-08-18).
Care is taken to avoid offering subcommands in the DWIM case.
