Yes. Of course, this is improvable -- before and after-change-functions
give me enough data to make it work better, although it will make the
cloning functions harder to write.

It is, however, fast enough for me to test whether it works from a user
interface POV which was what I needed. I was rather surprised, but it
appears to cause no noticable lag when I type even on my netbook.

And narrowing, and lots of things, I would have thought.
