Fix the path in the example usage to reflect reality.

loadmail(): Make max<0 mean there's no max instead of using
bunch-o-9's.  Also change the base command so that max is optional
(there'll be no max if not given).

Also, get rid of the .invalidate(None) call since 1) the method
doesn't accept a None argument anymore; 2) minimize() should do the
trick anyway.
