Hmm. By offhand looking at the code, I would agree with you that it
is hard to fix these bugs. When we talked in Paris, you said that you
considered the redisplay engine (relatively) well-written and worth
upgrading. Have you gained additional insight now, or were you having
other things in mind at the time?
Like getting your PhD done. :-)
