      // First, we must find any existing menu items that may

      // first construct the regex itself by replacing %views_arg

      // (which will be something like '#^(foo/%[^/]*/bar)$#') to
      // search through the existing paths.

        else {
          // This item already exists, so it must be one that we added.
          // We change the various callback arguments to pass an array
          // of possible display IDs instead of a single ID.
