Point taken.  It can be argued that a single token is insufficient for
classification.  Perhaps a message with only 1 significant token
should be rated as "Unsure".

If 1 token is insufficient, what is the appropriate minimum number of
tokens? Is it 2? or 5? or 10?  Assuming there is a minimum, it ought to
be configurable (as are bogofilter's other parameters).  Given
configurability, there's no way to prevent a bad configuration.

HTH,

David
