Bug, 0^0 is undefined in Maxima but 0^x is 0.

In Sage we've standardized on 0^0 == 1.

To start with, e.g. take a look at

http://trac.sagemath.org/ticket/10772

(and probably one of its follow-ups,
http://trac.sagemath.org/ticket/13786 ).

(There are plenty of related tickets, and IIRC we also had endless
discussions a couple of times on sage-devel.)
