# This version of update_references just updates the local branch names.
# We need to map these sensibly to remote names, but since this method
# is also used by gexport (which doesn't take a remote repo), that
# mapping probably needs to go elsewhere--which brings us to gpush....
#
# gpush takes an as-yet-unused branch name parameter.  A decent first
# approach would probably be to create a remote ref for the pushed-to
# repo with the same as the local branch name, bailing if the local
# branch doesn't exist.
#
# Before I undertake that bit, though, I'm seeking a quick "yup, that's
# the intent" or "nope, people will expect it to act like so" first.
