I still disagree.  Remember, -N and -S exist for people that are 
automatically updating the lists.  There's no reason to automatically 
update user-defined lists, that's what the stock goodlist/spamlist are 
for.

Hand-maintained db-files will be updated infrequently, if at all.  The 
only obvious purpose for such a file would be to download big spam DBs 
from the net, and there's no reason to ever update those.

Plus, I think there's easy ways to screw it up and accidentally mess up 
your goodlist or badlist too:

bogofilter -N --spamlist myspamlist <msg

If you insist, I think that an option to subtract a message from a given 
list could be implemented, without risking the trouble:

bogofilter --subtract --spamlist myspamlist <msg

This is the only possible way to correct a situation where you're only 
building a spam list (for net distribution), with no matching goodlist.
