Here's what I have so far. :-)

It needs to add 'None' as an alternative to all other places where
currently NAME occurs.
The Unix Makefile automatically regenerates Includes/graminit.h and
Python/graminit.c when you touch Grammar/Grammar.
For some mysterious reason, I didn't have to change the code generator
at all -- the NAME terminals and the 'None' terminal look the same to
it. :-)
