With this change, I see a dramatic change in font size -- the
vertical length of the post-font-name "p" is less than half of the
vertical length of the pre-font-name "p".  Admittedly, it's a bit
hard to tell since the post-font-name letters are in italics
rather than non-italics.

I'm using fontconfig 20090923 (the default in ubuntu 9.04), in
case that matters.  We currently issue a warning, but no error,
for this version.  Should it be an error instead?
