Add example to get "RUNNING: <testname>" when a test starts.

* doc/automake.texi (Alternative): remove obsolete footnote.

(Linking Multiple Yacc Parsers): new subsection.

Also add @shortcontents.
Also update texinfo-master-menu (for the first time in ages).

* configure.ac (AC_INIT): Bump version number to 1.16h.
* m4/amversion.m4: Likewise (auto-updated by "make bootstrap").

* configure.ac (AC_INIT): Bump version number to 1.16g for snapshot.

--with-python-sys-prefix is specified; otherwise, return to
previous behavior of using the GNU ${prefix} and ${exec_prefix}.

* doc/automake.texi (Python): document the new behavior.
* m4/python.m4 (AM_PATH_PYTHON): conditionalize use of Python's
sys.* values on the new option --with-python-sys-prefix.

* THANKS: update with missed recent committer.
* NEWS: mention yyerror decl in our tests now uses const.

Some of yacc error messages are const strings; it makes no sense for
yyerror to take a 'char *', it should be a 'const char *' as POSIX now
requires.
