Bug#783201: libcpan-meta-perl: clarify CPAN::Meta::History::Meta_* licensing

[Niko Tyni]

Package: libcpan-meta-perl
Version: 2.142690-1

Upstream version 2.142690 has this changelog entry:
  CPAN::Meta::History::Meta_1_0 through 1_4 are added as a permanent
    record of 1.x versions of the metaspec

These files all read
  This is a historical copy of the version 1.0 specification for F<META.yml>
  files, copyright by Ken Williams.

but there's no mention of their license.

The top-level LICENSE and README files state

    This software is copyright (c) 2010 by David Golden and Ricardo Signes.

    This is free software; you can redistribute it and/or modify it under
    the same terms as the Perl 5 programming language system itself.

which doesn't seem to apply to the files above due to the different
copyright holder information.

A quick search didn't turn up anything explicit about the license of
the documents, so I suppose we need to

- ask Ken Williams for an explicit license statement
- ask CPAN-Meta upstream to include that in the distribution
- include it in our debian/copyright file

Only filing at 'normal' as I expect this is just a documentation issue
rather than a real licensing problem.
