Thanx. I've incorporated your and Bjorn Pettersen's corrections.

Yes. Python doesn't care whether the object returned is a new object or an
old one, so it always DECREFs the object. It could conceivably check if the
object is the same, and only DECREF the old object if it isn't the same, but
that would mean the functions it calls need to sometimes return a borrowed
reference, and sometimes a new reference. Ugly.

Thanx for the feedback ;)
