Custom URLs for issue queues (for modules not in contrib)

Admin Menu links to the project URL via drupal.org for all installed modules. Some don't have an issue queue (project or module) on d.o though.

If we recognised a custom .info value when building the list for issue queues we could do this

name = MyModule
description = Custom module for Organization X
package = Custom
core = 6.x
issue_url = http://example.com/support

  // Add links to project issue queues.
  $links[] = array(
    'title' => 'Drupal issue queue',
    'path' => 'http://drupal.org/project/issues/drupal',
    'weight' => -10,
    'parent_path' => 'http://drupal.org',
  );
  $projects = array();
  foreach (module_list(FALSE, FALSE, TRUE) as $module) {
    $info = drupal_parse_info_file(drupal_get_path('module', $module) .'/'. $module .'.info');
    if (!isset($info['project']) && !isset($info['issue_url') || (isset($info['project']) && ($info['project'] == 'drupal' || isset($projects[$info['project']])))) {
      continue;
    }
    $projects[$info['project']] = 1;
    if (isset($info['issue_url'])) {
      $url = $info['issue_url'] ;
    }
    else {
      $url = 'http://drupal.org/project/issues/'. $info['project'];
    }
    // Filtering project versions via query string is not yet supported.
    // @see http:// drupal.org /node /97569
    // $url .= !empty($info['version']) ? '/'. $info['version'] : '';
    $links[] = array(
      'title' => check_plain($info['name']) . ' issue queue',
      'path' => $url,
      'parent_path' => 'http://drupal.org',
    );
  }
 

Maybe even test for "issue_url = none" and allow omission also.
