+
+       * src/gram.c: Remove comments that duplicate comments in gram.h.
+
+       When reporting useless rules and nonterminals, say "useless in grammar"
+       instead of "useless", and say "useless in parser" instead of "never
+       reduced".  Discussed starting at
+       <http://lists.gnu.org/archive/html/bison-patches/2007-10/msg00033.html>.
+       * NEWS (2.3a+): Mention this change.
+       * data/xslt/xml2text.xsl: Update output text and expected input XML
+       element names to match changes below.
+       * data/xslt/xml2xhtml.xsl: Likewise.
+       (xsl:template match="bison-xml-report"): Add missing entry in Table of
+       Contents: "Rules useless in parser due to conflicts".
+       * doc/bison.texinfo (Decl Summary): Reword a little.
+       (Understanding): Update example output for changes below.
+       * src/gram.c: (rule_useful_p): Rename to...
+       (rule_useful_in_grammar_p): ... this.
+       (rule_useless_p): Rename to...
+       (rule_useless_in_grammar_p): ... this.
+       (rule_never_reduced_p): Rename to...
+       (rule_useless_in_parser_p): ... this.
+       (grammar_rules_print): Update for renames.
+       (grammar_rules_print_xml): Update for renames.
+       (grammar_rules_never_reduced_report): Rename to...
+       (grammar_rules_useless_report): ... this since it is used for either
+       kind of useless rule.
+       * src/gram.h: Reword comments and update function names in prototypes.
+       * src/main.c (main): Say "rule useless in parser due to conflicts".
+       * src/print-xml.c (print_rules_never_reduced): Rename to...
+       (print_rules_useless_in_parser): ... this, and rename output XML
+       element "rules-never-reduced" to "rules-useless-in-parser".
+       (print_xml): Update for rename.
+       * src/print.c (print_results): Say "Rules useless in parser due to
+       conflicts".
+       * src/reduce.c (reduce_grammar_tables): Say "rule useless in grammar".
+       (nonterminals_reduce): Say "nonterminal useless in grammar".
+       (reduce_output): Say "Nonterminals useless in grammar".
+       Say "Rules useless in grammar".
+       (reduce_xml): Rename output XML element "useless" to
+       "useless-in-grammar".
+       (reduce_print): Don't report the count of grammatically useless rules
+       as "rules never reduced" just because %yacc is specified.
+       In the correct report of this count, say nonterminal(s) and rule(s)
+       "useless in grammar".
+       * tests/conflicts.at (S/R in initial): Update expected output.
+       (Defaulted Conflicted Reduction): Likewise.
+       (Unreachable States After Conflict Resolution): Likewise.
+       * tests/existing.at (GNU pic Grammar): Likewise.
+       * tests/reduce.at (Useless Nonterminals): Likewise.
