Bug#838896: libstring-copyright-perl: copyright extraction confused by itemized list

[Dominique Dumont]

Package: libstring-copyright-perl
Version: 0.003003-1
Severity: normal

Dear Maintainer,

licensecheck returns dubious information:
$ licensecheck --copyright src/strings/unicode_db.c
src/strings/unicode_db.c: GENERATED FILE
  [Copyright: there is clear notice in each]

unicode_db.c is indeed a generated file but has a © statement
(which used to be extracted).

Here's the header of the file:
+++++++++++++++++
*   DO NOT MODIFY THIS FILE!  YOU WILL LOSE YOUR CHANGES!
This file is generated by ucd2c.pl from the Unicode database.

from http://unicode.org/copyright.html#Exhibit1 on 2012-07-20:

I guess that String::Copyright is confused by the itemized list made of
(a) (b) and (c).

The whole file can be retrieved there:

All the best
