So the MSG_COUNT isn't decreased by any maintenance functions (-a -c -n)?

I assumed it was rebuilt if you reloaded the database from text.  But I 
guess this isn't case on further inspection.

I assume then for proper care and feeding of bogofilter, there really 
isn't much reason (rather, requirement) to use any of the maintenance 
utilities unless you have performance needs.

Am I close?
