We have a test case for this actually. It goes like this:

checking known breakage:
	(cd clone &&
	 git push origin new-name:new-refspec
	) &&
	compare_refs clone HEAD server refs/heads/new-refspec

Everything up-to-date fatal: Needed a single revision not ok 16 - push new branch with old:new refspec # TODO known breakage

In other words, we don't handle it at all. What we do handle a case similar to what you say, where we have already pushed part of the history of some-branch, and in that case we do indeed only push the needed objects.
