+       Some M4 cleanup in the testsuite.
+       Suggested by Eric Blake at
+       <http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00083.html>.
+       * tests/existing.at (_AT_TEST_EXISTING_GRAMMAR): Do not
+       complicate the code by distinguishing between a missing value
+       and an empty string value for an optional argument.  This fix is
+       allowed by the similar fix in AT_TEST_TABLES_AND_PARSE below.
+       * tests/local.at (_AT_TEST_TABLES_AND_PARSE): Merge into...
+       (AT_TEST_TABLES_AND_PARSE): ... this now that the special
+       arguments are not needed because of the following changes.
+       Fix stale comments.
+       Bison developers should use GNU M4 and should not use
+       POSIXLY_CORRECT when building the test suite, so do not
+       complicate the code by avoiding $10 and above.
+       Do not quote an empty string value for an optional argument, and
+       do not distinguish between a missing value and an empty string
+       value.

+       Style changes and factoring.

+       * src/reader.c: Factoring: assign_named_ref function.
+       * src/scan-code.l: Factoring and style changes. Rename
+       parse_named_ref to parse_ref. Use "c-ctype.h" from gnulib.
+       Use "unsigned" type for variant index. Improve readablity.
+       * src/scan-gram.l: Change error messages and add comments.
+       * src/symlist.h: symbol_list_null: New function decl.
+       * src/symlist.c: symbol_list_null: Implement here.
