This is a better version of the patch. As I was implementing the notification of
moderation, I realised this forking behaviour was far from ideal and could be
better. Now it does the forking similarly to how it is done for confirming
subscriptions while notifying the list owner. It, too, makes sending the
notification the lower priority, with the exit status representing whether it
succeeded in sending the mail to moderators.
The comments below still apply.

Normally a mail is sent to the subscriber if the address is already subscribed
to the list. If the \fB\-s\fR switch is used such a mail will not be sent.
-When neither \fB\-c\fR nor \fB\-C\fR are specified, subscription silently
-happens.
+Subscription may be moderated (if <listdir>/control/submod exists) unless the
