I have tried the stable -> unstable transition for a few fonts packages
(I chose completely at random ttf-inconsolata and ttf-tamil-fonts, but I
am quite sure it happens elsewhere):

 * ttf-inconsolata has a VERSION too low: the version in stable is
001.009-1 (and still has defoma hints), and the preinst removes the
hints only for upgrade from versions VERSION=001.001-2 or lower.

 * ttf-tamil-fonts has the correct removal (it seems), but it leaves
behind a file in /etc/fonts/conf.d.

Is the team interested in a (semi-automatic) testing of stable->unstable
upgrade that would check that all conffiles are correctly managed? I can
provide patches.
