Well, find-face returns a face object in xemacs. I'm proposing a new function 
to add to gnu emacs so that there's <rant>one fewer arbitrary
difference between
emacs and xemacs that causes inconvenience and unnecessary friction for 
those of us who code third-party applications or help users of both xemacs and 
emacs</rant>. If find-face in emacs didn't return a face object, it
wouldn't be doing
a very good job of compatibility, now. 

The proposed patch I outlined, and the stupid way in which it has to
differ across
emacs and xemacs, shows that there's a use for improving compatibility.
