Possible bug in "taxonomy_csv_line_import" function

Situation: Using a TAXONOMY_CSV_FORMAT_DEFINITION_LINKS import

Sample csv:

Tax|Tax|Topics & Keywords|||0|0|0|0
Banking|Banking|Topics & Keywords|||0|1|0|0|Tax

You have imported it once already and you reimport it (you can imagine some modification in other terms)

Possible bug:

While importing an existing term

// Import main term.
        $current_result = taxonomy_csv_term_import($term, $options['existing_items']);
		
        // Complete the term with the term id in case it's not been fulled.
        $term->tid = $current_result['tid'];
        // Save with name if identifiant was not set (else, it's already saved).
        if ($line[1] == '') {
          $result['name']['term'][$line[0]] = $current_result['name'];
          $result['tid']['term'][$line[0]]  = $current_result['tid'];
        }
        $result['msg'] = array_merge($result['msg'], $current_result['msg']);

if the term id is set then it's not added to the $result array. Afterwards the second term can't find the parent in the result array and it's added twice....

Two options:

1) add it to the result array whre it try to preimport a term

or

2) Modify step 7: Import each parent and check result.

if (isset($result['name']['term'][$line[1]])) {
            $term->tid = $result['tid']['term'][$line[1]];
          }
          // Pre-import is needed only when name and identifiant are different.
          else {//if (drupal_strtolower($line[0]) != drupal_strtolower($line[1])) {
            $current_result = taxonomy_csv_term_import(
              (object) array(
                'name' => $term->name,
                'vid'  => $term->vid,
              ),
              TAXONOMY_CSV_EXISTING_IGNORE_CREATE);
            $result['name']['term'][$line[1]] = $current_result['name'];
            $result['tid']['term'][$line[1]]  = $current_result['tid'];
            $result['msg'] = array_merge($result['msg'], $current_result['msg']);

            if (_taxonomy_csv_worst_message($current_result['msg']) < TAXONOMY_CSV_PROCESS_NOTICE) {
              break;
            }
            $term->tid = $current_result['tid'];
          }

Why only import it if the name and the identifiant are different? That makes that if they are the same and it was imported already it isn't load in the $result array.

So... would be the solution exchange this code for...

// Pre-import is needed only when name and identifiant are different.
          else {
            $current_result = taxonomy_csv_term_import(
