Help text not appearing on Arrange Tab

Just a heads up on a trivial bug. The help text does not appear on arrange tab of the admin controls.

You specified the wrong url in your hook_help():

...
    case 'admin/config/front/settings/arrange':
      return t('<p>Arrange the order in which roles will be checked for custom front page settings. Roles will be processed from top to bottom. To enable other roles you must first enable them in the !link.</p>', array('!link' => l(t('Settings tab'), 'admin/config/front/settings')));
...

It should be:

...
    case 'admin/config/front/arrange':
      return t('<p>Arrange the order in which roles will be checked for custom front page settings. Roles will be processed from top to bottom. To enable other roles you must first enable them in the !link.</p>', array('!link' => l(t('Settings tab'), 'admin/config/front/settings')));
