Log Message:
Anticipate None becoming a keyword in Python 2.3.  There are a few
functions with a default argument of the form None=None, as a speed
hack; this will break.

Note that in one case, None is not used in the function body; in
another case, None is used to pass an explicit 2nd arg to {}.get(),
but this defaults to None.  Draw your own conclusions...
