That is great news! I think my preference would be to move it to
github.com (I was actually in the process of doing this today - is it ok if I proceed?) and continue to be the upstream developer - there are some ugly corners I hope to gradually smooth out. I would hate for anyone to see the module Debian.Debianize.Finalize who didn't absolutely have to...
On the other hand, I'm fine with debian/patches if that is better for you than the github mechanisms. Mostly I don't want for there to be a fork - nobody has the time and energy for that. I'm pretty sure Debian specific patches belong in the upstream - after all, this is a Debian specific program! The stuff that says "lost in the mists of time" can certainly be removed - I'm positive nobody out there is still using them.
