Bug#928597: should support syntax for license exceptions in license short names

[Sébastien Villemot]

Package: libconfig-model-dpkg-perl
Version: 2.122
Severity: normal

Dear Mantainer,

If I use "GPL-3+ with Font-exception-2.0" as a license short name in my
debian/copyright file, I get:

$ cme update dpkg-copyright                                                                                                                                                   
Updating data...
Configuration item 'Files:"etc/fonts/*" License short_name' has a wrong value:
        value 'GPL-3+ with Font-exception-2.0' does not match grammar from model

But this is a perfectly valid syntax for a license short name, see:
 https://www.debian.org/doc/packaging-manuals/copyright-format/1.0/#license-short-name

Cheers,
