The attached patch by Holger Repp allows for an additional parameter
in the /etc/leafnode/config file which is the pathname for another
default message. The reason I am not willing to put this into the
nntpd.c is simply that (a) you don't get any groupname-dependent
information out of this, and (b) I cannot see that it is meaningful.

The patch is for leafnode 1.9.2.
