Well, caveat emptor.  I'm unwilling to any longer administer my own mail server
unless absolutely forced to, anyway.

Hmm, I didn't have that problem.  If you check out my blog post noted at the
beginning of this thread, I thiknk this is enough:

* X = the first message-ID in the message's "References:" header
(refers to the beginning of the thread if we're not at the beginning
and all MUAs are well-behaved).
* Y = the message-ID of the current message
* Set up a filtered folder showing everything whose message ID is X or
Y or that has X or Y in its references field.

Thanks; looks like I might be able to make this do some of what I want
(once I untwist your über-functional style and figure out what it
means) ;-)
