dc3dd copyright

[Christophe Monniez]

Here is a summary of the situation.

dc3dd is a patched version of gnu/dd from the gnu coreutils package.
dc3dd uses a lot of files from the coreutils package and some of them
maybe useless for dc3dd.

I tried hard to figure out what files are useless but I failed.

So I need to mention in the debian/copyright file all the authors of
coreutils files that are used in dc3dd.

In some cases, it's simple. For example, there are 324 files out of 447
in lib/ that are the same in coreutils and dc3dd.
But it left 123 files that I need to figure out if they are patched from
coreutils or the work of dc3dd author only.

My question is about the first case. If a file is a patched version of a
coreutils file, should I mention the dc3dd author in the Debian
copyright file, or the coreutils autho, or both ?
