    Reading changelogs... Done

[odd, why would [apt-listchages?] be reading changelogs during a purge?]

    (Reading database ... 177916 files and directories currently installed.)
    Removing dwww ...
1   dpkg - warning: while removing dwww, directory `/etc/dwww' not empty so not removed.
2   Purging configuration files for dwww ...
3   Purging configuration data in /etc/dwww/ ... done.

OK, but you need an additional message [numbers are mine]:

4   Removing directory /etc/dwww/ .
or something, to assure one that 1 has been fully treated, as 3 only
talks about files.

i.e. you do indeed remove the directory, but from 1+3, the user thinks
you forgot to.  So give better messages.
