confirm bugfix

A bug has been introduced into the confirm versions 1.2.7 - 1.3.0
resulting in the failure to put someone on the subscriber list after
succesful confirmation. In versions 1.2.7 - 1.3.0 I did some bugfixes
and improvements for the unsubscribe feature of confirm and missed to
test also the subscribe functionality which lets the newly introduced
bug leak through. If you use the versions mentioned above you should
upgrade to version 1.3.1 (ftp://ftp.pure.ch/smartlist) or apply the
attached patch to rc.request. confirm versions below 1.2.7 are not
affected.
