Incorrect id, self link and alternate link in the Atom comment feed of each entry

[peaceablewhale]

The id, self link and alternate link in the Atom comment feed of each entry is incorrect. Using an entry of the WordPress development blog,  http://wordpress.org/development/2007/10/wordpress-231/feed/atom/, as an example:

The following code is not correct...

<id>http://wordpress.org/development/comments/feed/atom/</id>
<link rel="self" type="application/atom+xml" href="http://wordpress.org/development/comments/feed/atom/" />
<link rel="alternate" type="text/html" href="http://wordpress.org/development" />

The correct code should be...

<id>http://wordpress.org/development/2007/10/wordpress-231/feed/atom/</id>
<link rel="self" type="application/atom+xml" href="http://wordpress.org/development/2007/10/wordpress-231/feed/atom/" />
<link rel="alternate" type="text/html" href="http://wordpress.org/development/2007/10/wordpress-231/#comments" />

Does anybody know how to correct them?

Replying to ionfish: Thanks for the fix. I have a comment on it:

the_permalink(); returns the permalink of the entry only. Should the alternate link refer to the comment part of the entry by adding "#comments" after the permalink?

Not all templates have an element with the id 'comments', but I imagine the developer who commits the fix will add it (or mention it here) if they feel it's appropriate (I suppose it would be in line with the behaviour of some other links functions).

Ideally we'd also include self and alternate links and id values for searches as well, rather than simply using the root values, but that was beyond the scope of the five minutes I had to write this in. We probably need a search_feed_link() function (a noticeable omission from r6365); I might make a new ticket and set about writing one.

A #comments anchor obviously isn't required for a theme, but WordPress assumes it's there when it creates many links (such as the comments link).
