Er, I think copying essentially random headers to other headers is
a bad idea. Mailman should leave the headers as untouched as possible.
Not even to placate stupid broken mailers that can't thread properly. :)

(I've already written a threading engine for my mailer that uses
In-Reply-To if there is no References header. It's trivial.)
