The current status in CVS is to pass {}, because there appeared to be
some case where a PyCFunction was not expecting NULL.  I assumed,
without checking, that {} was required and change the implementation
to always pass a dictionary to METH_KEYWORDS functions.  I could
change it back to NULL and see if I can reproduce the error I was
seeing.
