use index iterator to accomodate multivol extraction

For reasons unknown, the “tar path iterator” always terminates
after the last element of the first volume. In fact, it does so
even for multi volume archives if the last object in the first
volume extends into the second volume. In this case, the object
is completely extracted but extraction terminates.
