PEP 269 Implementation, rev.0

As per earlier discussions, I am going to take a whopping huge
intermission that will run August right out, and end my yearly yernings to
expose pgen to the Python public.  Therefore, I've submitted a provisional
patch for parser people to play with until next August (*smirk*).  Get it
while it's hot (ID 599331), and still in sync with CVS (not that there
are any radical changes):

Comments are requested.

Thanks!
