Comment (by stevenkword):

 @MikeNGarrett -- After having put some more thought towards it, I agree
 that creating a new hash would be messy so I've revised my approach.

 4575.diff adds a new methods specifically for returning the most recently
 modified post or comment from any given feed.  It uses the default
 WP_Query object to obtain a list of post object IDs displayed in the feed
 and then leverages `$wpdb->get_col()` to retrieve the most recently
 modified post/comment.
