register_post_type – rewrite / feeds, what’s it for?

In case it helps anyone…

I had misunderstood – the feeds argument of ‘rewrite’ was merely about the formatting of feed URLs (to use rewriting).

What I want is not to have a feed URL output in the <head> of my custom post type pages. The only way I have found to do this, is using

remove_action( 'wp_head', 'feed_links_extra', 3 ); 

although this will suppress the feed in other circumstances (categories etc), not just for my custom post type. If anyone knows how to do what I want I’d love to hear from you!
