To respond to myself here, the spec suggests *informatively* in two
places that :before and :after should default to pre-line (although
in one of them, for HTML only, which seems bizarre):
but it never says so normatively.

If we actually want this behavior, it should be stated normatively
(and then the tests would be correct).  If we don't, we should
probably take out the examples.
