Agreed.

Literally, $2 is "most-recently-configured-version".  I read this as
"none if there is no configured version", but it might as well mean
"none only if there never *was* a configured version".  This is why I
thought I needed to discriminate.

Note that I unsubscribed from all Debian lists for a while, so please Cc
me if you think that it's not sufficient for me to look it up in the
archive in a couple of weeks.
