Unless we explicitly ask for POST params with the "params" argument to
mkurl(), prevent them from propagating. (Can't think of situations when
we would want to propagate a POST param, but we err on the side of
flexibility so...)
Thanks to Thomas Berezansky for suggesting the CGI url_param() method of
filtering POST params.
