This is a patch which changes python's mailbox.Maildir class
to move processed messages form new/ to cur/. Although not 
expicity stated in http://cr.yp.to/proto/maildir.html 
all applications using Maildirs I'm aware of move messages 
form new/ to cur/ after the first reading of a message.
This patch gives you a way to get the same behaviour in python
by giving a third parameter to __init__. See 
mailbox.Maildir.__init__.__doc__
