Comment:

 In an effort to minimize comment "permalink" breakage,
 [attachment:8071.8.diff] does the following:

 * Restores 'page_comments'
 * Changes the default value for 'page_comments' from 0 to 1
 * Introduces a couple of new helper functions.
 `wp_get_top_level_comments_count( $post_id )` does what it says.
 `wp_get_comment_pages_count( $post_id )` gets the *canonical* comment-page
 count for a given post. By "canonical" I mean the count that is actually
 used when WP how to build comment pages (in `comment_template()`). This
 means that it respects threading as well as `comments_per_page`. It also
 doesn't require full comment objects. In these ways, it differs from the
 existing `get_comment_pages_count()`.
 * When `page_comments` is disabled, and the comment count for a post is
 above the (filterable) 'comment_paging_threshold', comment pagination is
 forced, with 'comment_paging_threshold' used as the per-page value.
