When finalizing changelogs for upload, I've found it very easy to forget
to update debian/NEWS as well, and have sometimes made uploads that
include "UNRELEASED" entries there.  Those are then presented to users,
which looks untidy.

Could `dch -r` perhaps also check the top entry in debian/NEWS to see if
it has the same version as the top entry in debian/changelog, and if so
then update it as well?

Thanks,
