Comment (by keesiemeijer):

 In [attachment:44212.2.patch] the function `wp_parse_list()` is introduced
 and is used by `wp_parse_id_list()` and `wp_parse_slug_list()`.

 With this function it now removes the empty values returned by
 `preg_split()`. You can also remove all the values that equal to false by
 setting the `$format` parameter to 'filter_false'. We could use this
 filter for `wp_parse_id_list()` as IDs are not supposed to have a value of
 0. I've left it as is for back compatibility.

 The other instances where `preg_split()` is used with the same regex
 should get their own ticket for replacing it with `wp_parse_list()`. This
 is because sometimes it's expected to have an empty value for empty
 strings.
 {{{
 array(
     0 => ''
 )
 }}}
