I'm thinking we have a bit of code rot happening here.  This comment:

seems to have little to do with the code which it is trying to
describe.  Or at least, I'm not sure this is the best we can possibly
do :(
Try to do it soon 8-)
Also, your email client is adding MIME goop to the emails which mine
(sylpheed) is unable to decrypt.  It turns "=" into "=3D" everywhere.
This:

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

I blame sylpheed for this, but if you can make it stop, that would make
my life easier, and perhaps others.
More care will take gmail later on.

Thanks
