* !sending_stream (an mta handoff to sendmail). But then we
* added the undisclosed recipients line which should only get
* written if writehdr is set, and not when we pass to a
* sendmail temp file. So pine_address_line has been changed
* so it bases its decision solely on the writehdr passed to it,
* and the logic that worries about Bcc and sending_stream
* was moved up to the caller (here) to decide when to set it.
*
* So we have:
* undisclosed recipients:; This will just be written
* if writehdr was set and not
* otherwise, nothing magical.
*** We may want to change this, because sendmail -t doesn't handle
*** the empty group syntax well unless it has been configured to
*** do so. It isn't configured by default, or in any of the
*** sendmail v8 configs. So we may want to not write this line
*** if we're doing an mta_handoff (!sending_stream).
*
* !sending_stream (which means a handoff to a sendmail -t)
* bcc or lcc both set the arg so they'll get written
* (There is also Lcc hocus pocus in pine_address_line
* which converts the Lcc: to Bcc: for sendmail
* processing.)
* sending_stream (which means an smtp handoff)
* bcc and lcc will never have writehdr set, so
* will never be written (They both do have rcptto set,
* so they both do cause RCPT TO commands.)
*
* The localcopy is independent of sending_stream and is just
* written if it is set for all of these.
