hook_requirements() is directly using t() even if initialize $t with the value returned from get_t()

token_requirements() initialize the value of the local variable $t, but in one case the code calls directly t().

    if ($duplicate_tokens = token_find_duplicate_tokens()) {
      foreach ($duplicate_tokens as $token => $modules) {
        $duplicate_tokens[$token] = t('@token (defined by modules: @modules)', array('@token' => $token, '@modules' => implode(', ', $modules)));
      }
      // ...
    }
