I have locally patched my Emacs to preserve undo info during revert, so
I completely agree it's desirable.  When I suggested the change it was
rejected (it's somewhere in the archive if you're interested, tho I can't
remember the thread title and not even when it took place, I'd say about
2 years ago).

Maybe having it as a (potentially buffer-local) option is a good idea.

What do people think?
