why would route set (the one recorded by record-route headers) change
because of gruu?  it doesn't in my tests.

in-dialog requests don't deal with those t_ functions.  after loose_route()
i use this:

   if ($du == "") {
        if (is_gruu()) {
            if (!lookup("location")) {
                send_reply("404", "Not Found");
                exit;
            } else {
                xlog("L_INFO", "Routing in-dialog $rm <$ru> from <$fu> to <$du>\n");
            };
