+Subject: [PATCH] Decrease the number of individual sites listed in log.
+
+By default 30 first servers are listed individually to system log, and
+then a count of the remaining items. With e.g. a NXDOMAIN based adblock
+service, dnsmasq lists 30 unnecessary ad sites every time when dnsmasq
+evaluates the list. But the actual nameservers in use are evaluated last
+and are not displayed as they get included in the "remaining items" total.
+
+Handle the "local addresses only" separately and list only a few of them.
+Remove the "local addresses only" from the general count.
