i think remote_url isn't used any more. Can you refactor a bit to avoid
computing it?

Yeah, I tried, and it makes surprising tests fail in surprising ways. I'm going
to leave that for the much larger wholesale SVN removal, which will also deal
directly with those tests.

       remote, remote_branch = self.GetRemoteBranch()
       target_ref = GetTargetRef(remote, remote_branch, options.target_branch,
                                 settings.GetPendingRefPrefix())
