You won't get a face with height 0 because the call to `match-string'
will throw an error if there is no match.  Try

(progn (string-match "^[0-9]+" "xxx") (match-string 0 "xxx"))

And in case it fails it would probably be better to use a fallback
value instead of throwing an error.  But unless there is evidence that
this actually can happen I'd rather leave the code as is.

Thanks for the suggestion nevertheless.  I am really grateful for such
feedback, especially if it helps ironing out bugs which show up only
on XEmacs.
