I also implemented this feature in https://github.com/gitlabhq/gitlabhq/pull/5933. Almost identical to this code actually. The other PR includes some specs, too.

Nice! I will defer to yours with two exceptions, noted at https://github.com/gitlabhq/gitlabhq/pull/5933/files#r8675206 and in the pull request conversation.
