Can we safely assume that all charsets folks will use with Mailman
will have us-ascii as a subset? It seems to be the case so far.
If so, I think the code I wrote can be loosened up a bit -- us-ascii
headers/footers can *always* be added to a message, so if the list's
language is US English, adding headers and footers should be fine no
matter what the charset.
If the list's language is not US English, though, we just simply
cannot add a header/footer blindly unless the message explicitly says
it's the same charset as the header/footer will be. Any other way
lyes madness. :)

Well, remember that old-style PGP bodies will have the whole:
===BEGIN PGP SIGNED MESSAGE===
blah blah
===BEGIN PGP SIGNATURE===
abcdef123456
===END PGP SIGNED MESSAGE===
thing going, so we can safely add headers/footers to these kinds of
messages, as they will be outside these ===VERY LOUD AREAS===.
I don't know how it works for S/MIME, frankly.
