Yes.

Currently you choose a code path with --protocol. The message is sent
only once. It is possible to iterate over To/Cc/Bcc/Newsgroups and
choose send it more than once. There are some tiny nasty bits though, I
don't know how to handle. For example:

--8<---------------cut here---------------start------------->8---

        my $to = ask("Who should the emails be sent to (if any)? ",
                     default => "",
                     valid_re => qr/\@.*\./, confirm_only => 1);
        push @initial_to, parse_address_line($to) if defined $to; #

        $prompting++;

+                    default => "",
+                    valid_re => qr/[\x20-\x7f]+/, confirm_only => 1);

sanitized/validated later
+       $prompting++;
 }
--8<---------------cut here---------------end--------------->8---

How to ask interactively where to send the message? With protocol set
early it is clear what we are trying to do. Any suggestions?

The other issue is that I am not sure (RFC?) if it is OK to send
To/Cc/Bcc headers in a NNTP message. Theoretically they should not break
things but...

I've sent this patch vi NNTP :) You've got it.
