Indeed, but I think that's the only question that's actually been asked
(Dan will hopefully correct me if I'm wrong).

I actually *expected* that `equal` on window configs would behave like
`eq`.  It would have never occurred to me (before I looked at the code)
that it could be different (although in retrospect, I can see reasons
why it could make sense).
