juggling user expectations

6.18: adde/mail/bcc info during a forward:
. how to build a mail system that
impl's blind carbon copy with no leaks?
. say you have that bcc'd email sent
and then you start to forward your view of it;
it shows both who it was sent to
and who it was cc'd to, but not the bcc's?
. wouldn't we want to give you the option?
(ie, you'd have to edit bcc if abstain)
but what if the naive user is not expecting it
even while the power user is demanding it ?
. do you notify the user that bcc is apparent in forward ?
require dialog before creating the forwarding process ?
