+JH/18 Bug 3068: Log a warning for use of deprecated syntax in query-style
+ lookups.
+
+JH/19 Fix TLS startup. When the last expansion done before the initiation of a
+ TLS session resulted in a forced-fail, a misleading error was logged for
+ the expansino of tls_certificates. This would affect the common case of
+ that option being set (main-section options) but not having any vriable
+ parts. It could also potentially affect tls_privatekeys. The underlyding
+ coding errors go back to 4.90 but were only exposed in 4.97.
