Summary: monstertrig makes bogus call to maxima-substitute

Initial Comment:
The call to subliss eventually tries to substitute (%cos simp) for D:

(%i2) integrate(cos(2*x)*cos(x),x);

         ((MTIMES SIMP) ((%COS SIMP) $X)
          ((%COS SIMP) ((MTIMES SIMP) 2 $X)))
         $X $X)
    2> (SUBLISS ((N . 2) (X . $X) (D %COS SIMP) (M . 1) (X . $X)
                 (B %COS SIMP) (A . 1))
                ((MTIMES) A
                 ((MPLUS)
                  ((MQUOTIENT)
                   ((%SIN) ((MTIMES) ((MPLUS) M ((MTIMES) -1 N)) X))
                   ((MTIMES) 2 ((MPLUS) M ((MTIMES) -1 N))))
                  ((MQUOTIENT) ((%SIN) ((MTIMES) ((MPLUS) M N) X))
                   ((MTIMES) 2 ((MPLUS) M N))))))
