Here's the updated debdiff against the Debian sudo 1.8.5p2-1 source.
I've incorporated Marc's feedback by dropping the Ubuntu-specific sudoers migration code in the preinst, postinst, and postrm.
I've verified that upgrading from 1.8.3p1-1ubuntu3.3 (Precise) and 1.8.3p2-1ubuntu2 (Quantal) work as expected.
Since I've done a few revisions now, I also went ahead and retested this revision in Quantal amd64 and i386 using test-sudo.py. It passed all tests.
