* data/skeletons/yacc.c (yysyntax_error): Change the nesting of `m4`
conditions slightly to make it more readable.
The generated C code stays unchanged.
* tests/regression.at: Use %expect to avoid warnings.
Set the keywords to facilitate running specific tests.
Use macros such as AT_YYLEX_DECLARE to facilitate tests for other
languages.
Likewise for AT_FULL_COMPILE.
In Texinfo. empty lines in multitable rows generate empty lines in the
output. Avoid them altogether.
With help from Gavin Smith.

* build-aux/cross-options.pl: Separate rows with empty lines.
So, to be more readable, generate a single line for each row.
Use Perl format to this end.
See the previous commit. This option should be removed, -o suffices.
* src/getargs.c (FIXED_OUTPUT_FILES): New.
Add support for it.
(getargs): Define loc, and use it.
This is safer when we need to pass a pointer to a location.
The name fixed-output-files is pretty clear: generate y.tab.c, as Yacc
does. So let's detach this from %yacc which does more: it requires
POSIX Yacc behavior.
This directive is obsolete since December 29th 2001
8c9a50bee1. It does not show in the
doc. I don't want to spend more time on improving its diagnostics, it
could be removed just as well as far as I'm concerned.
* src/scan-gram.l, src/parse-gram.y (%fixed-output-files): Detach from
%yacc.
Years ago we moved from 'look-ahead' to 'lookahead', and that alias
was kept for backward compatibility. But now that we use argmatch to
generate the documentation, that value clutters the doc.
* src/getargs.c (argmatch_report_args): Remove the
--report=look-aheads alias.
The doc says that -Dfoo=bar is the same as %define foo "bar". It is
not: the quotes are not added (and it makes a difference).
* doc/bison.texi (Tuning the Parser): Fix the definition of -D/-F
* src/getargs.c (usage): Likewise.
Let's clarify --help: use clearer "section" names, as in the doc.
Move --yacc to where it belongs.
* src/getargs.c (usage): Rename "Parser" as "Tuning the Parser", as in
the doc.
Rename "Output" as "Output Files"
Move --yacc to "Tuning the Parser".
* doc/bison.texi: Likewise.
It can now generate the usage message.
* src/complain.h (feature_fixit_parsable): Rename as...
(feature_fixit): this, for column economy.
Adjust dependencies.
(warning_usage): New.
Use it.
* src/complain.h, src/complain.c, src/getargs.h, src/getargs.c:
Use ARGMATCH_DEFINE_GROUP instead of the older interface.
The code is inconsistent: sometimes we pass by value, sometimes by
reference. Let's stick to the last, more conventional for large
values in C.
* src/scan-code.l: Pass locations by reference.
* configure.ac (DCFLAGS): Pass -g.
* data/skeletons/d.m4 (b4_locations_if): Remove, let bison.m4's one do
its job.
* data/skeletons/lalr1.d (position): Leave filename empty by default.
(position::toString): Don't print empty file names.
(location::this): New ctor.
(location::toString): Match the implementations of C/C++.
(yy_semantic_null): Leave undefined, the previous implementation does
not compile.
* tests/calc.at: Improve the implementation for D.
Enable more checks, in particular using locations.
* tests/local.at (AT_YYERROR_DEFINE(d)): Fix its implementation.
Sadly enough, AFAIK, there were never answers to the "More user
feedback will help to stabilize it" sentences. Remove them.
* src/getargs.c: IELR, canonical LR and XML output are here to stay,
and they are no more experimental than some other features.
* doc/bison.texi: Likewise.
Also remove "experimental" warning for Java, LAC, LR tuning options,
and named references.
* data/skeletons/lalr1.java: Use more conventional function names for
Java.
Prefer < and <= to => and >.
Use the same approach for m4 quotation as in the other skeletons.
Fix indentation issues.
* tests/calc.at, tests/java.at, tests/javapush.at: Fix quotation style.
(main): Use 'args', not 'argv', the former seems more conventional and
is used elsewhere in Bison.
Prefer character literals to integers to denote characters.
* examples/java/Calc.y: Likewise.
Travis answered favorably to my suggestion to provide a means to
disable git clone on some jobs (issue 7542). See
https://docs.travis-ci.com/user/customizing-the-build/#disabling-git-clone.
* .travis.yml: Disable git globally, enable it for i. the compile job,
and ii. the test job on ICC which needs the install-icc.sh script.
This is an experiment. Maybe more styles will be used (in which case
a short-hand function will be useful), maybe it will be just reverted.
* data/bison-default.css (.traces0): New.
* src/lalr.c (lalr): Use it.
See e3fdc37049: in C++ we generate
explicitly the code for the default action instead of simply copying
blindly the semantic value buffer. This is important when copying
raw memory is not enough, as exemplified by move-only types.
This is currently tested by examples/c++/variant.yy and variant-11.yy.
But it is safer to also have a test in the main test suite.
* tests/local.at (AT_REQUIRE_CXX_STD): Fix.
(AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS): Define/undefine
AT_BISON_OPTIONS.
* tests/c++.at (Default action): New.
