stash: introduce push verb

Introduce a new git stash push verb in addition to git stash save.  The
push verb is used to transition from the current command line arguments
to a more conventional way, in which the message is given as an argument
to the -m option.

This allows us to have pathspecs at the end of the command line
arguments like other Git commands do, so that the user can say which
subset of paths to stash (and leave others behind).
