It appears that the new code does *two* evaluations of the summand. This is
bound to lead to problems like this.... I thought we had discussed this a
long time ago, and in fact discussed this particular kind of problem.
For better or worse, Maxima semantics makes it the case that
eval(eval(<expr>)) is NOT the same thing as eval(<expr>).
