Bug#877766: lintian: more false positives in copyright-year-in-future

[Guillem Jover <guillem@debian.org>]

Package: lintian
Version: 2.5.54
Severity: normal

Hi!

The new copyright-year-in-future check is very prone to
false-positives. And I doesn't feel like white-listing context is
the best way to go around this. :/

ISTM that this check should only be performed on the Copyright field
for machine-readable files. Checking the License field text (or the
entire file for non-machine readable files) is too error prone.

Examples of this can be src:glide, or the thousands of tags emitted
from lintian.d.o, which to me are a sign the check is misguided.

Thanks,
Guillem
