Bug#1052259: licensecheck: GPL-3+ licences shown as GPL-3

[Peter B]

Package: licensecheck
Version: 3.3.9-1
Severity: normal
X-Debbugs-Cc: peter at pblackman.plus.com

Dear Maintainer,

Files containing short license names such as GPL-3.0+ are reported
as GPL-3 instead of GPL-3+

Example is dist/unix/strawberry.spec.in in package strawberry
https://salsa.debian.org/debian/strawberry/-/blob/master/dist/unix/strawberry.spec.in

This is the only example file I have now, but I have tried editing the file to
use various other short names such as;

GPL-3+
GPLv3+

The results are the same. The + suffix is not recognised as allowing a later
version of the license. All are reported as GPL-3


Regards,
Peter B
