  * Fetch packages even if they happen to already be installed
  Though obviously not if they have already been fetched.
  This lets people study the source for core packages that
  came with their compiler say, so they did not get have the
  sources downloaded via cabal-install. Fixes ticket #297.

    M ./Distribution/Client/Fetch.hs -6 +28
