I think we should accept comment-only changes in the patch. With those
changes comments are consistent with the code; otherwise code-readers
will get confused. I don't have a strong opinion about the comment +
code changes though. They may wait till changes in [1] get committed.
As Robert said, we may not want that to be an invariable rule.
