Loading with parent-only term in hierarchical taxonomy

I’m loading posts that belong to the parent term in a hierarchical taxonomy. If they do not belong to a child term, then they are not added to the list of term_ids to assign the post to.

I changed csv_importer.php around line 410 from:

if ($parent_ok) {
                    $child_info = $this->term_exists($child, $taxonomy, $parent_id);

To:

if ($parent_ok) {
                    if( !$child )
                      $term_ids[] = $parent_id;

                    $child_info = $this->term_exists($child, $taxonomy, $parent_id);

A bit cheap and dirty, but it did the trick for me.
