It's a matter of a 3-way merge, as cvs does it. The three files are:
  1) Old package version original config file
  2) New package version config file
  3) The installed config file (with your changes).

This would mean changing dpkg to keep pristine copies of installed
conffiles (file 1 above) so the comparison and merge could be done.

This is something I would love, but never have the time to do anything
about.
