Only files shipped by a package (i.e., appear in its .list file) can be
diff'ed, so if a configuration file was generated from scratch in a
postinst then apt-diff can't show a diff for it. But it does keep track
of how many files it has seen that aren't owned by any package, and
there is an option to print the list, so you can use that to see what
generated files are present in a directory tree. But at that point you
sort of have to know what you're looking for.
Sort of analogous to an untracked file in a VCS system.
