Probably because you sent it to spambayes-checkins.  All the *-checkins
lists on mail.{python,zope}.org share a single training corpus, and
their idea of ham is most likely diffs of Python code.

Luckily, the ever-vigilant Martijn Pieters noticed the false positive
and sent it on to spambayes-checkins anyways.  Thanks Martijn!

(And no, I don't have any plans to improve the training regime right
now; I put myself on enforced sabbatical from spam-fighting a month ago,
when I noticed it was taking over my life.)

Nice try, Tim, but no dice.  If a rejection from python.org says "looks
like spam", that's based entirely on Spambayes.  If it was my virus
detector gone awry, it would have said "looks like a virus" (or similar).
