This is just a quick note about something I noticed while reviewing: I was surprised that this code path would only trigger when `orig_head` is different from the null SHA-1, because in my mind, it is safe to update when we are on an unborn branch. However, I verified that the shell script does the same thing, so your transcription is faithful.
