22406,adjacent_posts_rel_link ignores $excluded_categories argument,adelval,,"The ticket subject is pretty obvious, I think, just by looking at the source in link-template.php:

{{{ 
function adjacent_posts_rel_link($title = '%title', $in_same_cat = false, $excluded_categories = '') {
    echo get_adjacent_post_rel_link($title, $in_same_cat, $excluded_categories = '', true);
    echo get_adjacent_post_rel_link($title, $in_same_cat, $excluded_categories = '', false);
}
}}}

The $excluded_categories should be passed to get_adjacent_post_rel_link just as they come, not as an empty string. 

Possible use cases of having the bug fixed: 
- want to exclude a category from almost everywhere (because it has a single place in the blog), but it keeps appearing in the rel links.
- don't want to help robots discover posts from those categories through the rel links (robots.txt is not enforceable). ",defect (bug),new,normal,Awaiting Review,Template,2.8,normal,,has-patch,alvarodelval1@…
