make it clear that the ref in the dictionary is the name of the ref on the
remote service. e.g. if you have Ref('refs/heads/master'), that will push the
ref named 'refs/heads/master' on the remote. e.g. there's no refspec translation
which happens.

Done.

is there a minimum git version which is required for this syntax?

[Vadim Sh., 2014/07/30 20:15:35]

I don't think so. Help page for 1.7.5 already mentions this syntax:
http://git-scm.com/docs/git-push/1.7.5

+    for r, c in refs_and_commits.iteritems():
+      r.update_to(c)
