Subject: [PATCH] cabal unpack --pristine

Without --pristine, cabal will update the package's cabal file if a newer
one is available in hackage. But that can break applying patches.
Especially since the new version from hackage can apparently have dos line
endings, while the version from the tarball doesn't.
