Optional title in comments_popup_link

[anonymousbugger]

The comments_popup_link function in wp-includes/comments-functions.php does not currently permit to submit a title tag for the hyperlink; it is assumed that the text of the hyperlink will be self-explanatory. But some templates (see ​http://www.somefoolwitha.com/) use uninformative titles, and need a title tag. Could this be added as a last argument to the function?
