[Spambayes] Need testers!

[Tim Peters]

Following my own advice (read TESTING.txt if you haven't yet <wink>), I'm
giving up on this one and will rip the supporting code out of the project
(adjust_probs_by_evidence_mass will go away):

> [Classifier]
> adjust_probs_by_evidence_mass: True
> min_spamprob: 0.001
> max_spamprob: 0.999
> hambias: 1.5

The reports from the people who have tested this (for which I thank you!)
simply don't show a consistent and significant improvement.  Jeremy put the
last nail in its coffin today, by running a reasonable but ham-heavy 10-fold
c-v test where it was a pure loss for his f-n rates.  This is a conflated
result because he's also tokenizing more header lines (which I can't do,
because doing so is "too good" on my mixed-source corpora), which is
something we all want to do eventually.  But even without that, the case for
making this change wasn't strong enough.

Thanks for the help!
