Eelco Dolstra 52bf9b86bb * In nix-store: added query `--referers-closure' that returns the
closure of the referers relation rather than the references
  relation, i.e., the set of all paths that directly or indirectly
  refer to the given path.  Note that contrary to the references
  closure this set is not fixed; it can change as paths are added to
  or removed from the store.
