Applied to HEAD. I'm still not quite satisfied with the error message:

  ereport(ERROR,
          (errcode(ERRCODE_DATATYPE_MISMATCH),
           errmsg("unexpected return value from plpython procedure"),
           errdetail("void-returning functions must return \"None\"")));

Suggestions for something better?
