+       * conform/conformtest.pl: Handle "optional-" at start of lines in
+       one place rather than duplicating several cases.  Handle each
+       format of "macro" line with initial "optional-".
+
        * conform/conformtest.pl: Only accept expected constant or
        optional-constant values with "==".  Parse all "constant" lines in
        one place.  Parse all "optional-constant" lines in one place.
