I don't know what is the right answer here. However I hope that
the 2 or 3 people who do know will comment. Otherwise I might
get inspired to try to figure it out and change it myself.
If I'm not mistaken the simplification of radicals was modified
in the recent past (not more than 2 years ago). I forget what
was at issue then, and what changes were made; but maybe
before making further changes it would be useful to review.
