are n-ary.
Changes some examples to demonstrate it.
(Calc++ Parser): Use %param.

(SC_ESCAPED_CHARACTER): Warn if length is wrong.
* tests/input.at (Bad character literals): New test group.
Implement, document, and test the replacement of %error-verbose
by %define parse.error "verbose".
* data/bison.m4 (b4_error_verbose_if): Reimplement to track the
values of the parse.error variable.
Make "simple" its default value.
Check the valid values.

(PERCENT_ERROR_VERBOSE): New token.
Support it.
* src/scan-gram.l: Support %error-verbose.
* doc/bison.texinfo (Decl Summary): Replace the documentation of
%define error-verbose by that of %define parse.error.
* NEWS: Document it.
* tests/actions.at, tests/calc.at: Use parse.error instead of
%error-verbose.

http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00033.html
* data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
New.
(b4_percent_define_use): New.
Use it where applicable.
* data/c++.m4: Replace uses of the variable "namespace" by
"api.namespace".
Default the latter to the former.
* doc/bison.texinfo (Decl Summary): Document "namespace" as
obsolete.
Document api.namespace.
Use @samp to document %define uses, keep @code for identifiers.
* NEWS: Likewise.
* tests/c++.at, tests/input.at: Test api.namespace instead of
namespace. (The tests passed with namespace.)
* doc/bison.simple (Decl Summary): Document token.prefix.
(Calc++ Parser): Various fixes.
Formatting changes.
Use token.prefix.
Introduce a macro TOKEN to shorten the code and make it more
readable.
(Calc++ Scanner): Adjust.
* NEWS (Variable token.prefix): New.
For now, just api.push-pull and lr.keep-unreachable-states.
Maintain old names for backward compatibility.
* NEWS (2.5): Document.
* data/c.m4 (b4_identification): Update comment.
* data/yacc.c: Update access.
* doc/bison.texinfo: Update.
* etc/bench.pl.in (bench_push_parser): Update use.
* src/files.c (tr): Move to...
* src/getargs.c, src/getargs.h (tr): ... here because I can't
think of a better place to expose it. My logic is that, for all
uses of tr so far, command-line arguments can be involved, and
getargs.h is already included.
* src/main.c (main): Update access.
* src/muscle_tab.c (muscle_percent_define_insert): Convert old
variable names to new variable names before assigning value.
* src/reader.c (reader): Update setting default.
