If one goes beyond ASCII at all, I really don't see a good reason not
to include all Unicode whitespace characters. And with my author hat
on, I think selectors probably *should* consistently use "all Unicode
whitespace characters" as their definition of white space.

(I might make an exception for U+0085, which is almost certainly *not*
NEXT LINE but a mistranscode of ELLIPSIS.)
