The Lisp code would be unnecessarily complicated.  And having a
display property on each character will slow down redisplay, because
handle_stop will be called for each character.  Having too many
intervals on buffer text is also best avoided for other reasons
(memory etc.).

I don't like such an implementation.  It's a kludge at best, IMO.
Please let's not go that way.
