HiI was triaging through lintian tagged bugs and came across this. I locally ran lintian (master branch from salsa) on nvidia-graphics-driver and this false positive is not showing up anymore even though debian/bug-script still has the following string:
"<<<<<<<<<< $file >>>>>>>>>>"
UDD's lintian also doesn't show this false positive anymore:
https://udd.debian.org/lintian/?packages=nvidia-graphics-drivers
So I believe this bug can be closed.
