is_ssl() broken -> https forced

Reading http://ww.wp.xz.cn/support/topic/ssl-enabled-by-default-for-loginadmin-how-to-remove the exact same problem is still occurring in the latest version of WordPress (3.3.1).

I am hosted on an suPHP system where I don’t have access to their config (linux/apache).

in wp-includes/functions.php:

function is_ssl() {

        if ( isset($_SERVER['HTTPS']) ) {
                if ( 'on' == strtolower($_SERVER['HTTPS']) )
                        return true;
                if ( '1' == $_SERVER['HTTPS'] )
                         return true;
        #} elseif ( isset($_SERVER['SERVER_PORT']) && ( '443' == $_SERVER['SERVER_PORT'] ) ) {
        #        return true;
        }
        return false;
}

The commenting out of the last check for SERVER_PORT fixes the problem that https is forced for all links, style sheets, images etc. which breaks my installation as I don’t have an SSL certificate.

This issue is 2 years old – please look into correcting this?
