PHP notices and undefined variables oh my!

When running the Coder Tough Love review, I get the following notices:
# notice: Undefined variable: potentially_inside_a_hook_menu in /home/davereid/Projects/drupal6/sites/all/modules/contrib/coder_tough_love/coder_tough_love.module on line 171.
# notice: Undefined variable: potentially_inside_a_hook_menu in /home/davereid/Projects/drupal6/sites/all/modules/contrib/coder_tough_love/coder_tough_love.module on line 176.
# notice: Undefined variable: potentially_inside_a_hook_menu in /home/davereid/Projects/drupal6/sites/all/modules/contrib/coder_tough_love/coder_tough_love.module on line 183.

function _coder_tough_love_admin_menu_descriptions(&$coder_args, $review, $rule, $lines, &$results) {
  foreach ($lines as $line_number => $line) {
    $line = implode(' ', $line); // concat'd parts.
...
    // if we're inside, look at the line and check for an admin path.
    if ($potentially_inside_a_hook_menu && preg_match('/\[[\'"]admin\//', $line)) {
      $potentially_found_an_admin_path = $line_number; // used in the error.
    }

Should be changed to:

function _coder_tough_love_admin_menu_descriptions(&$coder_args, $review, $rule, $lines, &$results) {
  foreach ($lines as $line_number => $line) {
    $line = implode(' ', $line); // concat'd parts.
    $potentially_inside_a_hook_menu = 0;
...
    // if we're inside, look at the line and check for an admin path.
    if ($potentially_inside_a_hook_menu && preg_match('/\[[\'"]admin\//', $line)) {
      $potentially_found_an_admin_path = $line_number; // used in the error.
    }
