Thanks to a hint from Erik ("... an mss problem of some sort"), I've
managed to make the problem go away, by doing
  echo mtu 1496 >/net/ipifc/1/ctl

I hope to come back to this when I have more time, because I don't
like not understanding why this works.  As nobody else has said they
have the same trouble, there may be something amiss in my adsl gateway.
