+	* ospfd.c (ospf_network_match_iface): Rewrite code for clarity
+	while trying not to change semantics.  Add ifdefed-out code to
+	avoid matching ppp interfaces whose destination address does not
+	also match the prefix under consideration, to help out people with
+	problems due to as-yet-unfixed bugs with p2p interfaces coming and
+	going.
