Comment (by mdgl):

 Sorry, but I noticed a couple of issues with this in further testing:

 1) As I suspected, the use of get_post_type() fails with empty post type
 archives (because the global $post is not set). In this case, we output an
 invalid link (because of issue 2 below). To find the post type, we need to
 go via the queried object instead (all a bit messy!).

 2) The two uses of isset() later in function feed_links_extra() don't work
 as expected because functions such as get_post_type_archive_feed_link()
 can return false rather than null. I think these two calls should be
 replaced with !empty().
