  * Change the PackageIndex invariant so the buckets are ordered
  Each bucket holds packages with the same name case-insensitively.
  Previously each buckets was internally unordered. Now they're
  ordered by the full package id which means first by package name
  case-sensitively and then by version.

    M ./Distribution/Simple/PackageIndex.hs -27 +41
