Yeah, I think they are equivalent, but I agree yours is a little more
readable. I'll switch it in my re-roll, and I will go ahead and set the
REF_KNOWS_PEELED bit when we see a peel line. That code should not be
triggered in general, but it is the sane thing for the reader to do, so
it makes the code more obvious and readable.
