It is possible to get this simplification with the help of of the
evaluation flag lognegint or the function rectform:
(%i1) log(-1),lognegint;
(%o1) %i %pi
(%i2) rectform(log(-1));
(%o2) %i %pi
(%i5) log(exp(%i*%pi)),lognegint;
(%o5) %i %pi
But i have thought about an implementation of this special value too.
Remark: The value of the option variable domain does not influence much
of Maxima. Only the exponentiation is handled differently.
