Comment (by ocean90):

 Using `array_keys()` like in [attachment:26511.14.diff] is fine.

 [attachment:26511.15.diff] adds a missing switch to
 `wp_notify_postauthor()` and adds `test_switch_to_locale_en_US()` which is
 currently failing. `get_available_languages()` doesn't include `en_US`
 since there are usually no language files for `en_US`.
