Comment (by rachelbaker):

 @Latz The `comments_template()` function is tricky because the variables
 set may be used in your theme's `comments.php` file. Example: I can see
 `$comment_author_url` used in `theme-compat/comments.php`.

 Before any of the globals or local variables are removed from
 `comments_template()` some research and testing will need to be done
 across the theme directory.
