workaround for ${1+"$@"}.
* doc/autoconf.texi (Shell Substitutions): Explain it.
From Oliver Kiddle and Peter Stephenson.
Have M4sh perform minimal shell sanitizing.
* lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
part into...
(_AS_PREPARE): this new macro.
(AS_PREPARE): New.

* tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
Adjust Autoconf and Autotest.
* lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
* lib/autotest/general.m4 (AT_INIT): Likewise.
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
Invoke _AS_PREPARE (not AS_PREPARE) in addition to

Use this M4sh to generate Autoconf's shell scripts.
* tests/wrapsh.as: New, precursor of wrapsh.in.
* tests/Makefile.am: Include lib/freeze.mk to get the dependencies
on Autotest and M4sh.
($(TESTSUITE)): Use $(autotest_m4f_dependencies).

(handle_m4): don't.
* lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
(M4sh): Rely on M4sugar.
(Autotest, M4sh, M4sugar): Use frozen files.
(&file_name_is_absolute): New, wrappers around routines from
File::Spec.
Use and export them.
(&find_configure_ac): Optionally take a directory where to look at.
* bin/autoreconf.in (&parse_args): Trim the configure.ac part of
the arguments.
Default @ARGV to `.', not find_configure_ac.
(&autoreconf): Argument is a directory.
Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
* doc/autoconf.texi (autoreconf Invocation): Update.
passed on command line, defaulting to ./configure.ac if present.
(&maybe_autoreconf, File::Find): Remove, unused.
(&autoreconf): If autoconf is not used, don't try to trace.
Remove, dead.
* bin/autoreconf.in (&autoreconf): Do not run gettextize when
`intl' is already present, as it refuses unless --force.
(&parse_args): Use -I, --include instead of the old Autoconf
options.
($localdir, $autoconf_dir): Remove.
(@include): New.
(&maybe_autoreconf): New, to preserve $_ for File::Find.
ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
(_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
builddir, buildpath, top_builddir, and top_buildpath.
(_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
the current directory.
* lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
variables *before* changing the current directory.
Skip nonexistent dirs.
* doc/autoconf.texi (Preset Output Variables): Document these
variables.
* lib/autotest/general.m4: Do not reset AT_victims.
Don't compute at_srcdir nor at_top_srcdir.

* tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
Remove.
* tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
* tests/wrapsh.in, tests/autoupdate.in: New.
* tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
* configure.ac: Build the position independent wrappers.
* man/Makefile.am: Now that test wrappers are position
independent, use them and drop dark envvar magic.
Map --localdir, --autoconf-dir onto it.
Forward autom4te's options instead of interpreting them.
* bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
There is no such envvar since the inception of autom4te.cfg.
* bin/autom4te.in (&parse_args): Uniquify `@include'.
* bin/autoupdate.in: Adjust, and perform more control.
* tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
* tests/autoconf: Dittowise.
