Lintian tag information: copyright-with-old-dh-make-debian-copyright (type: pedantic)

Description (from lintian-explain-tags)

The copyright file contains the incomplete Debian packaging copyright
boilerplate from older versions of dh_make. (C) alone is not considered a
valid copyright notice in some countries. The word Copyright or the ©
symbol should be used instead or in addition to (C).

Copyright notices like this are, in any country that's a signatory to the
Berne Convention, not required to claim copyright on a work, but their
presence may allow claiming additional damages should a copyright case go
to court. If you provide a notice, you may as well provide one that's
legally recognized in a broader range of countries.
