OK, thanks for the feedback. In case it's useful to anyone else
migrating away from defoma, what i finally came up with (for
ttf-fifthhorseman-dkg-handwriting) was:
---------------------
FIRST_VERSION_NO_DEFOMA=0.13-3
FILE=/etc/defoma/hints/ttf-fifthhorseman-dkg-handwriting.hints
if [ "$1" = upgrade ] || [ "$1" = install ] && dpkg --compare-versions "$2" lt-nl $FIRST_VERSION_NO_DEFOMA;
then
if [ -x /usr/bin/defoma-font ]; then
if [ "$1" = upgrade ]; then # no need to defoma-font purge-all if we aren't upgrading
defoma-font purge-all $FILE
fi
fi
rm_conffile ttf-fifthhorseman-dkg-handwriting $FILE
fi
---------------------
Note that i needed to wrap the defoma-font purge-all line as well,
so that i would properly handle the case where the sysadmin:
0) installs an old defoma-ized version
1) removes it, leaving conffiles
2) installs a new non-defoma version
without that extra test, the final installation would fail with these error messages:
0 pip:~# dpkg --install /home/dkg/src/ttf-fifthhorseman-dkg-handwriting/ttf-fifthhorseman-dkg-handwriting_0.13-3_all.deb

hope this helps other folks with the migration.
