PYTHON_VERSIONS_ACCEPTED and the march of time

[Tom Spindler <dogcow%babymeat.com@localhost>]

While attempting to get net/nicotine running, I noticed it
had PYTHON_VERSIONS_ACCEPTED = 23; after some digging, I found
that this was originally due to requiring threading in python,
and simply hadn't been updated (as far as I can tell) to allow
24 as well.

My question is this: is this actually a Good Thing? Would it be
better to change most most of these to python>=0.1 (or whatever)
rather than having to go through and change all of these entries
manually whenever a new version of python comes out?
