How to avoid ^- in maxima output? (Leo Butler) [Martin Kraska]

Leo, thanks for the agreement. Yes, it is sensible to include the code
changes. For the future, I guess, just adding rules to sm_rules in our
session init would be sufficient, wouldn't it? Then we do not need to bother
with updates. 

The only direct change was made to the match pattern in order to resolve
different interpretation of a^b^c in Maxima and SMath:

matchdeclare([sm_x],true,sm_y,lambda([e],if is(numberp(e) and e<0 and e#-1)
or is(not(atom(e)) and (op(e)="-" or op(e)="^")) then true else false));

Thanks again for your help. 

Martin
