This requires that the AutoAddSubs=true in sbbsecho.ini (the default) and if
you don't want an area file created/updated with new subs, just set new option
AutoAddToAreaFile=false.
Both of these options default to true which is the same as the previous
behavior: if you have a link that configured to hub for a msg group, any subs
not already in the area list/file will be considered new and added dynamically.
So what's new here is that you can set SBBSecho not to create or update an
area file and SBBSecho will run just fine if no area file exists or contains no
area definitions.
