That's a nice idea, I like it.

Probably there should be a customization
`org-babel-python-nonsession-return-style', which could take on the
values 'require-return (old behavior), 'last-statement (session style),
or 'auto (detect if there is return statement).

While technically a breaking change, I think 'auto would be a reasonable
default, since it would only change the behavior on the unusual edge
case where the user deliberately returned "None" by omitting a return
statement.
