When in non-commutative (aka `matrix') mode calc calculates
(a b)^-1 to be a^-1 b^-1 instead of the correct b^-1 a^-1.
Actually there is a more general bug. It calculates (a b)^n
to be a^n b^n. I think this rule should be removed when a and
be don't commute. Furthermore a special rule should be included
that deals with the case n=-1.

people in the arena here, you know, were underprivileged anyway, so
this--this (she chuckles slightly) is working very well for them.
