Fix some bugs when using "$@" when there might be zero positional
arguments in cases where this matters.

* lib/autotest/general.m4 (AT_INIT):
Use Zsh alias to work around problem.
* tests/atgeneral.m4 (AT_INIT): Likewise.
* tests/c.at: We can't have zero arguments, so remove workaround
that is not portable to Zsh.
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
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.
(AS_INIT): Invoke AS_SHELL_SANITIZE.
* 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
AS_SHELL_SANITIZE.
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).
(wrapsh.in): New target.
* bin/autoconf.as: New, precursor of autoconf.in.
(autoconf.in): New target.
* lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
(_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
Use dnl, not the KILL diversion.
Extracted from...
(AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
(AC_CONFIG_LINKS): here.
Adjust.
Don't use the KILL diversion, as it kills spurious output, which
results in failures being hidden.
Use m4_defn where appropriate.
(AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
after the second argument.
Use m4_defn.
* lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
syntax, as it is provided by M4sugar.

back on AS_DIRNAME to compute prefixes otherwise; this is
roughly what mkinstalldirs does. That way, we need not have
our own filename disassembler. The old disassembler did not
work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
