I was wondering whether someone may be annoyed by renumbering
whenever overview is rebuilt.  But my understanding is that
it won't take so much time in renumbering for each of overview
methods, and I think we can ignore that behavior.  So, I'm
going to also modify to leave flag file which will be examined
by rc.news if -r needs to be added or not.  Any comments?
