if the taxonomy term is unused do not list in menu

here's a one-line change that keeps unused terms from showing up in the jump menu:

in jump.module replace the old jump_menu_get_taxo_options function with

function jump_menu_get_taxo_options(&$options, $vid) {
  $tree = taxonomy_get_tree($vid);
  foreach ($tree as $term) {
    if (taxonomy_term_count_nodes($term->tid) !=0) {
      $options[taxonomy_term_path($term)] = $term->name;
    }
  }
}
