Threading MH messages

Threading MH messages

[Jason R Mastaler]

Why is it that Gnus doesn't like to thread replies that are composed
with MH?  I've noticed this for a long time now.  Take these three
summary buffers for example.

!A [  31: Lars Magne Ingebrigt] Qua Vadis, Quassia?
R  [   8: Vinnie Shelton      ] Re: Qua Vadis, Quassia?
 
O  [  41: Cedric Jaboulet     ] pb with rcvdist
O  [  15: Frank Swasey        ] Re: pb with rcvdist

R  [  21: Dave Golden         ] smapd address parsing fixes 
R      [  13: Rick Murphy         ] 
 
The second message of the first two buffers was composed with MH and
thus weren't threaded.  The second message of the third buffer was
composed with Windows Eudora and was threaded fine (like with most
other MUAs).  Thus, MH seems to be the exception.  This is especially
annoying in large mailing lists where I'm following a thread and then
later find a stray reply pages and pages down because it wasn't added
to the thread.  In most of these cases, the message indeed turns out
to be an MH message.

As I learned the hard way a long time ago... MH doesn't maintain
References by default.  It can be done without too much difficulty.
Unfortunately, you'll find that you're likely the only one who does it
so it only helps thread messages that you've replied to.  This is one
of the reasons I eventually gave up on MH as my primary mail reader.
Attached is a replcomps that maintains a References header.  I forget
where I got the appropriate bits from, though Jerry Peek is most
likely the source.  At one point I could actually explain how it
works, but I'm not sure I can do that now.

I've not seen that.  I have seen, however, that MH will append a space 
to the subject on replies!  That breaks Gnus' subject threading.

I once fixed a friend's MH config not to do that, but I don't remember 
now what I did.

Was this with a really old version of MH?  I've not noticed this with
MH 6.8.3(4) or nmh.
