CountGlyphs was originally written a long time ago, before
we had page variables and the like.

Yes, it seems like it should be trivial to do this, but it currently 
isn't.  :-(

I can probably fix that.  But even after fixing it, there will be
the caveat that the count won't be very precise, since we can't
really count things coming from (:include:), (:pagelist:), trails,
and other such markups.

Well, once you get a) working, b) works also.  But getting
a) to work does mean that the counts have to be saved as an attribute
somewhere, because we *really* don't want to be rendering the markup
and counting the words for every page we encounter in a pagelist.  :-)

The reason the CountGlyphs recipe can work now is because the
{$Words} markup only works on the current page (and, of course, we
have the text of the page already available and rendered in order to
be able to determine the count).
