Directory lists the feeds inside an OPML, not the OPML

Popular still counts an OPML as one feed, since everyone subscribed to it
counts for every feed inside and they would bury the rest. The directory is
for finding a show, so it lists them one by one and never the OPML. A feed
inside an OPML that looks private is hidden with it.
