[Python-3000] Need volunteer to update patch 1607548 (optional argument annotations)

[Guido van Rossum]

Tony Lownds created the original patch but (probably due to Thomas
Wouters' recent merge) the patch doesn't apply cleanly any more. Tony
hasn't responded on SF yet. Neal Norwitz added a lot of useful
commentary to the SF item too. Perhaps someone can run with this?
