It now is. Since the fen shortcode operates before including an image link to drawdiagram.php, it will use the length of the longest rank if the ranks are divided up by forward slashes and a value for cols has not already been supplied. This behavior is not built into drawdiagram.php itself, which will just use the default value if none is supplied. Here are some examples without any value for cols being specified.
