+
+       Extract the parsing of user actions from the grammar scanner.
+       As a consequence, the relation between the grammar scanner and
+       parser is much simpler.  We can also split "composite tokens" back
+       into simple tokens.
+       * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
+       * src/scan-gram.l (add_column_width, adjust_location): Move to and
+       rename as...
+       * src/location.h, src/location.c (add_column_width)
+       (location_compute): these.
+       Fix the column count: the initial column is 0.
+       (location_print): Be robust to ending column being 0.
+       * src/location.h (boundary_set): New.
+       * src/main.c: Adjust to scanner_free being renamed as
+       gram_scanner_free.
+       * src/output.c: Include scan-code.h.
+       * src/parse-gram.y: Include scan-gram.h and scan-code.h.
+       Use boundary_set.
+       (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
+       (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
+       which is now, again, a separate token.
+       Adjust all dependencies.
+       Whereever actions with $ and @ are used, use translate_code.
+       (action): Remove this nonterminal which is now useless.
+       * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
+       (grammar_current_rule_action_append): Use translate_code.
+       (packgram): Bound check ruleno, itemno, and rule_length.
+       * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
+       (last_string, last_braced_code_loc, max_left_semantic_context)
+       (scanner_initialize, scanner_free, scanner_last_string_free)
+       (gram_out, gram_lineno, YY_DECL_): Move to...
+       * src/scan-gram.h: this new file.
+       (YY_DECL): Rename as...
+       (GRAM_DECL): this.
+       * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
+       * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
+       (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
+       (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
+       Move these declarations, and...
+       (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
+       these to...
+       * src/flex-scanner.h: this new file.
+       * src/scan-gram.l (rule_length, rule_length_overflow)
+       (increment_rule_length): Remove.
+       (last_braced_code_loc): Rename as...
+       (gram_last_braced_code_loc): this.
+       Adjust to the changes of the parser.
+       Move all the handling of $ and @ into...
+       * src/scan-code.l: here.
+       * src/scan-gram.l (handle_dollar, handle_at): Remove.
+       (handle_action_dollar, handle_action_at): Move to...
+       * src/scan-code.l: here.
+       * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
+       scan-code.h, scan-code-c.c, scan-gram.h.
+       (EXTRA_bison_SOURCES): Add scan-code.l.
+       (BUILT_SOURCES): Add scan-code.c.
+       (yacc): Be robust to white spaces.
+
+       * tests/conflicts.at, tests/input.at, tests/reduce.at,
+       * tests/regression.at: Adjust the column numbers.
+       * tests/regression.at: Adjust the error message.
+
+2006-06-06  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+       * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
+       Use Akim's wording from
+       <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
+
+2006-06-06  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+       Between Bison releases, manually append `+' to the previous Bison
+       release number, and use that as a signal to automatically print the
+       ChangeLog's CVS Id keyword from --version.  Discussed starting at
+       <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
+       * ChangeLog: Add Id header.
+       * configure.ac (AC_INIT): Append `+' to `2.3'.
+       * src/.cvsignore: Add revision.c.
+       * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
+       (BUILT_SOURCES): Add revision.c.
+       (revision.c): New target rule.  This file defines a new global variable
+       named revision.  It initializes it with either the Id from ChangeLog
+       or, if VERSION doesn't contain `+', with the empty string.
+       * src/getargs.c (version): Print the value of revision.
+       * src/revision.h: Extern revision.
+
+2006-06-05  Paul Eggert  <eggert@cs.ucla.edu>
+
+       * NEWS: Version 2.3.
+       * configure.ac (AC_INIT): Likewise.
+
 2006-05-30  Paul Eggert  <eggert@cs.ucla.edu>
 
        * data/glr.c (YYRECOVERING): Define to be a function-like macro
        Copying and distribution of this file, with or without
        modification, are permitted provided the copyright notice and this
        notice are preserved.
