Yes, I prefer A as well.  It just means we'll have to further split
hairs on the semantics of relative selectors. :/

I think this needs to be done by a separate "absolutizing" algorithm
(separate from the current one) that converts "foo" into "foo" (no
change), "> foo" into "foo"-but-only-matches-elements-without-parents,
and convert "+ foo" and "~ foo" into "" (matches nothing).  (Other
combinators like || and /for/ also turn into matching nothing.)

fantasai, what do you think?
