Fix some bugs when using "$@" when there might be zero positional

arguments in cases where this matters.

* bin/autoconf.as: Rewrite so that the problem does not come up.
* lib/autoconf/programs.m4 (AC_CHECK_PROG): Likewise.
* lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
* lib/autotest/general.m4 (AT_INIT): Likewise.

* bin/autoheader.in: Use 'case' statement to work around problem.
* bin/auto4mte.in: Likewise.
* bin/autoreconf.in: Likewise.
* bin/autoscan.in: Likewise.
* bin/autoupdate.in: Likewise.
* bin/ifnames.in: Likewise.

* doc/autoconf.texi (Shell Substitutions): Document the problem.

* 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.
