 Currently, some (most?) themes have a translatable list item separator for
 displaying a list of categories or tags. See an [source:tags/4.7.2/src/wp-
 content/themes/twentyseventeen/inc/template-tags.php?marks=65#L58 example
 in Twenty Seventeen]:
 {{{
 /* translators: used between list items, there is a space after the comma
 */
 $separate_meta = __( ', ', 'twentyseventeen' );
 }}}
 One of ru_RU translation team contributors made a point that list item
 separator is a locale property, and it doesn't make much sense to
 translate it separately in multiple projects.

 We could probably add it as a property of `WP_Locale` class, in addition
 to `::number_format['thousands_sep']` and
 `::number_format['decimal_point']`, and there should be a public function
 like `number_format_i18n()`, e.g. `get_list_item_separator()`, for plugins
 and themes to use. Thoughts?
