How to make clickable the URL’s on comments area?

Hi!!

I want to make clickable the URL’s on the comments/answers.

If I write in my functions.php the following:

add_filter( 'comment_text', 'make_clickable');

doesn’t work.

If I write:

add_filter( 'the_content', 'make_clickable');

works, but also make clickable in the question area, and I only want the answers/comments section.

There is a way to do it?

Thanks.
