It already exists as http://www.pmwiki.org/wiki/PITS/00571 .  There's also 
a proposed recipe for it at http://www.pmwiki.org/wiki/Cookbook/InlineDiff,
which I haven't had a good opportunity to examine yet.

Yes, highlighting of rendered markup is extremely difficult.

Overall I'm still looking for people to highlight other wiki engines
that perform word-level diffs so that I can get some idea of how they
do it.
