Sorry, I haven't heard of such a beast.  The closest I've seen is the "block
comment" reflowing facilities in various Python editors.  For very long
lines with clear structure (lists, tuples and dict constructors; function
calls), I suppose you could do a lot worse than to feed them to Emacs,
injecting a newline after every comma.  Then they'll line up the way Guido
would type them by hand <wink>.
