  * Make the default SavedConfig contain empty rather than default ConfigFlags
  We do not want to pass a load of default command line flags. We only want
  to pass flags where we're overriding the defaults.
  Also it's because old Cabal versions do not understand new flags.

    M ./Hackage/Config.hs -4 +4
