🚀 go-pugleaf

I have my auto-folder-alist set up such that it usually guesses what folder I
want to put a message in based on its subject.  But sometimes someone will
change the subject to something useless, like "hey, it still doesn't work."
So this thought occurred to me: wouldn't it be spiffy if you could do
auto-filing based on References: lines?  Like, I don't know, somehow I 
mention that this message goes to this file, and VM remembers this, and as
I read, it collects the tree of messages which refer to that one (and so on)
and defaults the folder accordingly.

It should probably use the <...> stuff contained in an In-Reply-To field,
for those poor saps with less studly mail readers. :-)

Anyway, just an idea.  I'd still like to have real sorting and some hooks
before this...  Actually, before just about anything...
