[Spambayes] hammiefilter just started failing

[Tim Stone - Four Stones Expressions]

The 'correct' solution to this problem is a retrain.  But that's just not

statistics dudes are gonna have to weigh in on this one, because these 
parameters are used in the combining scheme, and fooling with them has 
consequences.  Tim?  Gary?  Rob?  - TimS
