#   Test the ability to append an item to the list.
#   Tests we plan are:
#      Append item and check that:
#      1)   The count of items is incremented by 1.
#      2)   The last item is the one we added.
#      3)   Append comment ensure that size of index is not
#           increased.
#
BEGIN {plan tests=>3}
