I wasn't aware of that class - I agree, it seems like a perfect choice.

We could switch to just "c" (which is nice, since it's then 'a', 'b', 'c')
and we'd then match the Python distribution itself.  In that case, this
addition might even be worth submitting as a distutils patch.  (Although
from a quick look, it's a case of adding a single character ('c') to a
regular expression...)

That should be simple, too.  It's just .version + .prerelease to get (eg)
(1,1,0,'a',1), and then a simple conversion of 'a'->'alpha', etc.

There's also the 'check for new version' stuff.  I guess that could also
move to __init__.py - I gather that just means that importing any of the
spambayes.* modules will import that as well, right?  As long as it doesn't
actually do any work on import, it doesn't seem like that would hurt.

Assuming no-one else pipes up with objections, would you like to make the
changes, or shall I?
