Bug#789074: Regression: licensecheck fails to parse copyright if a / is contained

[Didier Roche]

Package: devscripts
Version: 2.15.5
Severity: important

Dear Maintainer,

Since 2.15.5, licensecheck --copyright doesn't report copyrigthed file 
including
/.
Most of Qt packages (and files generated through Qt tools) contains:
   Copyright (C) 2013 Digia Plc and/or its subsidiary(-ies).
Which is then not parsable anymore to licensecheck.

Removing the / makes the copyright holder reported.

The commit introducing this regression is
https://anonscm.debian.org/cgit/collab-maint/devscripts.git/commit/?id=97ac51f54568728618695b92907a8ac4b87a1709,
and more especially that line change:
- if ($match !~ m%^\s*$copyright_disindicator_regex%ix) {
+ if ($match !~ $copyright_disindicator_regex) {


If we revert that one, with devscript 2.15.5, I can get the digia 
copyright back:
   [Copyright: 2014 Digia Plc and/or its subsidiary(-ies)]

I'm unsure about that change (and the other optimizations related into 
that commit), so I'm not proposing reverting that one right away.
I guess we can introduce one test for that use case.

Tell me if I can be of any help.
