1663 The value is t if the message was newly initialized; otherwise, nil.

1676 when the message is initialized.

1678 If `mail-default-reply-to' is non-nil, it should be an address (a string);
1679 a Reply-to: field with that address is inserted.
1680
1681 If `mail-archive-file-name' is non-nil, an FCC field with that file name
1682 is inserted.
1683
1684 The normal hook `mail-setup-hook' is run after the message is
1685 initialized. It can add more default fields to the message.
1686
1687 The first argument, NOERASE, determines what to do when there is
1688 an existing modified `*mail*' buffer. If NOERASE is nil, the
1689 existing mail buffer is used, and the user is prompted whether to
1690 keep the old contents or to erase them. If NOERASE has the value
1691 `new', a new mail buffer will be created instead of using the old
1692 one. Any other non-nil value means to always select the old
1693 buffer without erasing the contents.
1694
1695 The second through fifth arguments,
1696 TO, SUBJECT, IN-REPLY-TO and CC, specify if non-nil
1697 the initial contents of those header fields.
1698 These arguments should not have final newlines.
1699 The sixth argument REPLYBUFFER is a buffer which contains an
1700 original message being replied to, or else an action
1701 of the form (FUNCTION . ARGS) which says how to insert the original.
1702 Or it can be nil, if not replying to anything.
1703 The seventh argument ACTIONS is a list of actions to take
1704 if/when the message is sent. Each action looks like (FUNCTION . ARGS);
1705 when the message is sent, we apply FUNCTION to ARGS.
1706 This is how Rmail arranges to mark messages `answered'."
