Summary: matrix_element_add with ratmx  : true

Initial Comment:
Using a user defined value for matrix_element_add and
ratmx bound to true, we get a Lisp error. Example:

  (%i1) matrix_element_add : lambda([a,b], max(a,b))$
  (%i2) m : matrix([a,b],[c,d])$

This is OK (ratmx : false)

  (%i3) m.m;
  (%o3) matrix([max(a^2,b*c),max(a*b,b*d)], ...)

This is a bug:

  (%i4) m.m, ratmx : true;
Maxima encountered a Lisp error:
