Comment (by neoxx):

 Hmm, I think with the current implementation of `wp_dropdown_languages()`,
 finding out if the select holds any options is only possible by an ugly
 string comparison.

 Therefore a filter in `wp_dropdown_languages` would not help in case
 `$languages` is cleared by said filter to avoid extra markup in user-
 edit.php. Changing the implementation of `wp_dropdown_languages()` to
 something that can be captured with `empty()` would help, though.

 I'm not sure what's the policy on selects, are they supposed to return an
 empty select `<select></select>` w/o any option at all or would an empty
 string be alright? If so, what's recommended - empty string, null or
 false?
