I tried that.  If the forwarded message has a c-t-e of base64, and the
message/rfc822 part could be safely said to have a c-t-e of 7bit, the
forwarded message ends up with 8bit and the message/rfc822 ends up
with no q-t-e header.

Note!  What follows is complete messages with all headers interspersed
with comments.

Here's the message I forwarded (it hasn't been sent.  I just forwarded
it from the nndraft:queue mail group):

For completeness, here's the same message after having been sent, and
having been converted from base64 to 8bit by sendmail:

Forwarding this message results in q-p c-t-e on the message/rfc822
part (which should be 7bit) and no c-t-e on the forwarded message
(should be q-p or base64):
