-       Simplify handling of '.' and '-' after unbracketed named references.
-       * doc/bison.texinfo (Mid-Rule Actions): Mention that periods and
-       dashes make symbol names less convenient for named references.
-       * src/scan-code.l:
-       (handle_action_dollar): New arg textlen.  All callers changed.
-       (handle_action_at): Likewise.  Also, args are pointers to const.
-       (ref_tail_fields): Remove; no longer used.
-       (letter): Now includes '-' and '.', since this is for Bison
-       identifiers.
-       (id): Now the simpler traditional defn, since letters now include
-       '-' and '.'.
-       (c_letter, c_id): New defns.
-       (ref): Use c_id for unbracketed IDs.
-       (<SC_RULE_ACTION>): Simplify, now that the distinction between
-       Bison and unbracketed IDs are now in the regular expressions.
-       (VARIANT_BAD_BRACKETING): Remove.
-       (VARIANT_NOT_VISIBLE_FROM_MIDRULE): Renumber.
-       (find_prefix_end): Remove, replacing with ....
-       (identifier_matches): New function.
-       (variant_add): Use it.  Omit EXPLICIT_BRACKETING arg; no longer
-       needed.  CP arg is pointer to constant.  All callers changed.
-       (show_sub_messages): Remove args CP, EXPLICIT_BRACKETING, DOLLAR_OR_AT.
-       New arg TEXT.  All callers changed.  Do not worry about showing
-       trailing context.
-       (parse_ref): Args CP, RULE, TEXT are now pointers to const.  New
-       arg TEXTLEN.  Remove arg DOLLAR_OR_AT.  All callers changed.
-       Simplify code now that the regular expressions capture the
-       restrictions.
-       * src/scan-gram.l (letter, id): Adjust to match scan-code.l.
-       * src/symlist.c (symbol_list_null): Arg is now pointer to const.
-       * src/symlist.h: Likewise.
-       * tests/named-refs.at (Misleading references): These are now caught
-       by the C compiler, not by Bison; that's good enough.  Adjust test
-       to reflect this.
-       (Many kinds of errors, Unresolved references): Adjust expected
-       diagnostics to match new behavior.  The same errors are caught,
-       though the diagnostics are not quite as fancy.
-       ($ or @ followed by . or -): Likewise.  Also, Make the grammar
-       unambiguous, so that diagnostics are not complicated by ambiguity
-       warnings.
-
        Fix minor problems encountered by a fresh bootstrap.
        * data/glr.c, data/yacc.c: Do not use apostrophes in '#' comments,
        as they confuse xgettext, which tries to parse them as C character
