The comments_link_feed allows you to alter the link to the comments section of a post within the context of a feed.

When the ‘comments_link_feed’ filter is called, it is passed once parameters: the list item containing the powered by link.

<pre>add_filter( 'comments_link_feed', 'filter_function_name', 10 );

function filter_function_name( $link) {
    // Manipulate comment link
    return $link;
}

Where ‘filter_function_name’ is the function WordPress should call when the filter is run. Note that the filter function must return a value after it is finished processing or the result will be empty.

filter_function_name should be unique function name. It cannot match any other function name already declared.
