`facexp' and `stopex' now working



Hi,

It is a great thing to make these packages working.
However, I could not go through patched facexp.dmo, nether with maxima-5.6 nor
with cvs version.
Demo breaks at the C(10) of facexp.dmo ( in earler version it breaks  
just after applying facsum, at C(4) ).
I have  
(D9) C D Q X Y Z + 2 C D M P X Y Z + C D M N X Y Z + C D Q W Y Z

                                              2                  2
 + 2 C D M P W Y Z + C D M N W Y Z + C D Q U V  Z + 2 C D M P U V  Z

              2                                                      2
 + C D M N U V  Z - C D Q U Z - 2 C D M P U Z - C D M N U Z + C D U V  Y

                  2        2
 + C D U Y + D E F  + C E F  - D E + C E + B C D

(C10)                FACSUM(EXP3, C, D, [U, V, [Z, [M]]])

What can be wrong with it?
