[New-bugs-announce] [issue14740] get_payload(n, True) returns None

New submission from Bob Glickstein <bob.glickstein at gmail.com>:

Passing both a value for i and decode=True to email.message.Message.get_payload(), when self is a multipart, returns None when it should return a string.  The reason is that an is_multipart() test is done on self when it should instead be done on the selected payload part.  Here's a patch that fixes this:
