One might think that this introduces a logic error in "git stash
doesnotexist" now dispatching to a non-existing "stash_doesnotexist" or
something, bu tI see that earlier (omitted from context) in the function
there's an exhaustive lit of push/save/pop etc. which guards against
this, is is that correct?
