Thanks for the advice.
I'll keep looking---I think I need to find the code that applies
outativity) for antiderivatives. If somebody knows where this code is, let
me know ($1 for tapping a switch with a mallot and $9,999 for knowing
switch to tap). My fix only changes (simplify ... ) to ($expand ... 0 0),
so I'd guess the code was already cynically patched by its author :(
