I think it is a good solution!

Something like this then:

case "$1" in
install|upgrade)
if dpkg --compare-versions "$2" le "$LASTVERSION"; then
	if [ -e "$CONFFILE" ]; then
		if [ `md5sum "$CONFFILE" | sed -e \"s/ .*//\"` = "$oldmd5sum"; then
			echo >> "$CONFFILE"
                fi
        fi
fi
...

What do you think? We need to calculate the current md5sum for that version and include
it in the $oldmd5sum variable. Or do you think we should use the
  old_md5sum="`dpkg-query -W -f='${Conffiles}' $PKGNAME | sed -n -e \"\\\\' $CONFFILE '{s/ obsolete$//;s/.* //p}\"`"
line instead?

Best regards,

// Ola
