Inserting fixup paragraphs at the end of the file violates the Debian
standard ordering, where copyright paragrahs are ordered from least to
most specific. In order to fix this, we can define the "broadness" of
each Files pattern in a paragrahs, then split up the paragraph and
insert into the copyright file at positions that maintain the
broadness ordering.

Fixes apertis-issues#519.
