Bug#866223: devscripts: Add support for codenames to dch

[Yves-Alexis Perez]

Package: devscripts
Version: 2.17.6
Severity: normal

Hi,

the stable release team ack'ed me a package upload to oldstable, and
requested that I target the upload to 'jessie'. Unfortunately, it seems
that debchangelog doesn't know about codenames:

=====
corsac at scapa: dch -r -D jessie
dch warning: Recognised distributions are: unstable, testing, stable,
oldstable, experimental, {testing-,stable-,oldstable-,}proposed-updates,
{testing,stable,oldstable}-security, jessie-backports, stretch-backports
and UNRELEASED.
Using your request anyway.
dch: Did you see that warning?  Press RETURN to continue..
=====

Could it be added at one point?

Thanks in advance and regards,
-- 
Yves-Alexis
