Bug#675874: [debchange]: unnecessary "libdistro-info-perl is not installed" messages

[Jakub Wilk]

Package: devscripts
Version: 2.11.8
Severity: minor
User: devscripts at packages.debian.org
Usertags: debchange

$ dch -D UNRELEASED -i foo
libdistro-info-perl is not installed, Debian release names are not known.
libdistro-info-perl is not installed, Ubuntu release names are not known.


But dch did recognize the release name (otherwise it would emit another 
warning), so I don't see what are these messages for.

Also: I use Debian. I couldn't care less about Ubuntu release names.
