   Well, Peter will have to speak to the relative speed of this method
as opposed to using (member) against a list of whitespace characters,
but you could use:  (char-property 'input-whitespace? c), where "c" is
the character in question.
   This requires OpenJade 1.3, as 1.2.2 will simply return false for
every character.
