Thanks for that: it worked, but as written it put the browser into an
infinite-redirect loop (is drupal_goto() meant to avoid that?) Changing
the if statement to:

  if ((!$user->uid) && ($_GET['q'] != 'user/login'))

fixed the loop. I suppose e.g. (arg(0) != "user") instead would permit
user/register to be visited?

Cheers,
