decremented when a post is deleted

 The {{{update_posts_count()}}} function is used to update a blog's post
 count. When a post is added to the database the {{{post_count}}} value is
 incremented as expected. However, when a post is deleted, the
 {{{post_count}}} value isn't decremented.

 This is because the {{{_update_posts_count_on_delete()}}} function, which
 calls {{{update_posts_count()}}} is hooked to the {{{delete_post}}}
 action.

 {{{delete_post}}} fires immediately **before** a post is deleted from the
 database.

 Therefore, the query performed in {{{update_posts_count()}}} to get the
 post count is run at the wrong time.

 The solution is to use the {{{deleted_post}}} hook instead of the
 {{{delete_post}}} hook.
