Prepare two repositories, src and dst, the latter of which is a
clone of the former (with tracking branches), and push from the
latter into the former, using --lockref=name (using tracking ref for
"name" when updating "name"), --lockref=name:value, --lockref=name:
(i.e. check creation), and --lockref (using tracking ref for
anything that we update).
