mistake in description of function generate_board_url

Hi,

on the following page:

http://area51.phpbb.com/docs/code/phpBB3/_includes---functions.php.html#functiongenerate_board_url

function generate_board_url is described this way:

void generate_board_url ([bool $without_script_path = false])

But when you look at

function generate_board_url($without_script_path = false)

in functions.php, you see return $url;

$url is a string, so correct would be:

string generate_board_url ([bool $without_script_path = false])

Thank you
Wolfgang
