the current behaviour is to use this pvar for

current message buffer will still be used as an input), but we could
extend it to be used for input also if this is useful.
i think it would be useful especially if sdpops functions could also
be made operate on the pv. then there would no need to call
msg_apply_changes(). the pv could be initialized from $rb and when all
calls that manipulate the body have been made, the pv would be assigned
to $rb.
