?# being appended to redirect paths

In 5.x-1.2 there was the following line in path_redirect_init:

drupal_goto($r->redirect, ($r->query ? $r->query: NULL), ($r->fragment ? $r->fragment : NULL), $r->type);

In 5.x-1.x-dev, the equivalent line in path_redirect_check:

drupal_goto($r->redirect, $r->query, $r->fragment, $r->type);

Not doing the NULL check means that url() appends the # and ? characters to the end of every request which has no query or fragment.
