Comment:

 Dug in a bit here.

 `wp_rel_ugc()` is attached to the `pre_comment_content` filter which
 happens before the comment is saved. However, the function that makes
 plain text URLs clickable (`make_clickable()`) is hooked onto
 `comment_text`, which happens when the comment is output.

 It looks like `rel="nofollow"` is hardcoded within `make_clickable()`.
 This could be fixed by simply adding `ugc` to that (which
 [attachment:"48022.2.diff"] does).

 On first glance, `make_clickable()` is only used for comment content in
 Core. However, I'm not sure how it is being used by plugins and themes in
 the wild.
