+
+       In the grammar scanner, STRING_FINISH unclosed constructs and return
+       them to the parser in order to improve error messages.
+       * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
+       SC_BRACED_CODE, SC_PROLOGUE): Implement.
+       * tests/input.at (Unclosed constructs): New test case.
+       * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
+       seen.
+
+       * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
+       unused global.

+
+       Handle string aliases for character tokens correctly.
+       * src/symtab.c (symbol_user_token_number_set): If the token has an
+       alias, check and set its alias's user token number instead of its own,
+       which is set to indicate the alias.  Previously, every occurrence of
+       the character token in the grammar overwrote that alias indicator with
+       the character code.
+       * tests/input.at (String aliases for character tokens): New test.

+
+       * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.

        * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
