Merge branch 'tg/demote-stash-save-in-completion'

The command line completion (in contrib/) has been taught that "git
stash save" has been deprecated ("git stash push" is the preferred
spelling in the new world) and does not offer it as a possible
completion candidate when "git stash push" can be.

* tg/demote-stash-save-in-completion:
completion: make stash -p and alias for stash push -p
completion: stop showing 'save' for stash by default
