Add a debconf-show --priorities packagename
which would list the priority of each item, low, medium, etc. too.

Also
       The most common use is "debconf-show packagename", which displays all
       items in the debconf database owned by a given package, and their
       current values.  Questions that have been asked already are prefixed
       with an '*'.

The star seems to mean items that are not in their default state and
will get asked about and not skipped upon the next run of
dpkg-reconfigure. Perhaps say that instead.
