Cabal for GHC 7.8

[Manuel M T Chakravarty]

Thanks, Herbert.

I eventually noticed that it the Cabal repo is a submodule, but I wasn’t aware of the Git’s support to rewrite URLs.

To answer your questions: cloning from GitHub is useful as I can fork the repos on GitHub. At haskell.org, I need to use branches, which I don’t like.
