Comment 4 for bug 156185

Automatically assuming a user wants a specific action done to their customised config files is Just Plain Wrong, and we will never do it, however if *you* want something specific done to yours, you may add "force-confold" "force-confdef", etc (see "man dpkg" for force options, and "man dpkg.cfg" for what to do with them) to /etc/dpkg/dpkg,cfg

We give you the rope to hang yourself on this one, but we're not prepared to tie it around your neck without your permission. :)
