----------
The following verbs may be used to extract headers/messages from readable mail recipients/players;
:display_seq_headers (message sequence, current message number, last_read_date)
Does a @mail listing of the given message sequence. If current message
number is given and the sequence includes it, we mark it with a `>'.
Likewise if the sequence includes any new messages (i.e., dated after
last_read_date), these are also indicated as such.
display_seq_full (message sequence, preamble)
Does a @read listing of the given message sequence. Each message is preceded
by preamble.
=> {new current message number, new last_read_date}
:messages_in_seq (index)
=> {n, msg}
:messages_in_seq (message sequence)
=> {{n_1,msg_1},{n_2,msg_2},...}
where the n_i are message numbers and the msg_i are messages in transmission
format (see `help mail-format')
:list_rmm ()
Does an `@unrmm list' listing of messages in .messages_going
