The postrm script checks whether ucf is in the path, and if not it only
removes the file.  Since the internals of caching are not documented
(and probably aren't supposed to be, anyway?), we can't do anything about
the cached file.

On the other hand, ucf can't remove the directory together with its
contents when the package is purged:  It doesn't know whether the
package that the files belong to is purged or only removed.

So this bug probably needs to be open until dpkg provides ucf's
functionality.
