I started digging into ./maintainers/scripts/find-tarballs.nix and
found that there was just small changes needed to make it output all
fetch* derivations, not just fetchurl ones (unless I'm mistaken --
haven't fully verified it).

However, due to evaluation problems in nixpkgs and a stack overflow,
it's unuseable :-(

The code is here:

In the top of the file I list the problems I faced.

Any suggestions?

Can we have a bounty for implementing "nix fetch-sources --recursive
$expr"? I'll pay! :-)
