Summary: e-mail<->usenet gateway Reply-To header (PR#303)

I'm running a plain e-mail<->usenet gateway.
When someone replies to a usenet post through the list, his e-mail client sets
an In-Reply-To: header instead of a Reply-To: header. This causes newsreaders to
improperly thread messages.

I inserted the following bit into Mailman/Handlers/ToUsenet.py at around line
82:

    # if the message is a reply to a previous post, change the header so
    # that newsreaders can thread it properly
    if msg.getheader('in-reply-to'):
        msg.headers.append('References: %s\n' % msg.getheader('in-reply-to'))
        del msg['in-reply-to']

I'm happy to say that this solved the problem.
 
(before you laugh at me, take note that I never looked at python before.)

Sigh.  Very doubtful I'll get to look at the threading
issues before MM2.1 final.  I'll address this again after
the release.

Changing the group to 2.1 beta because I want to look at
threading issues for gated messages before 2.1 final is
released.

What a coincidence! I had the same problem and I looked 
into the code, then modified it to work properly. The 
coincidence is that my patch is *identical* to yours. So, 
for sure it works :-)

Message:
RFC 2076 says nothing about using In-Reply-To for news, so it might not be a bad idea to copy In-Reply-To to References when gating a message from mail to news.

Message:
This sounds like the email client in question is broken.  Mine for example, correctly inserts References: headers and the news readers properly thread the messages.  I'm not inclined to cater to broken email or news clients.
