tests: work around a ksh bug w.r.t. ${1+"$@"}
Fixes automake bug#10898. See also the older (much older) thread:
<http://lists.gnu.org/archive/html/automake-patches/2009-12/msg00036.html>
At least the AT&T and OpenSolaris versions of the Korn shell, as well
as the /bin/sh from OpenIndiana 11, have a strange bug regarding the
expansion of ${1+"$@"}: when exactly *one empty* argument is passed to
a script run by one of this shells, inside that script ${1+"$@"} will
expand to *nothing*, rather than to to the single empty string, as
one would expect (OTOH, $# will correctly expand to 1). This buggy
behaviour was causing a spurious failure in our testsuite (test 6 in
't/automake-cmdline.tap'). Work around it.
* t/wrap/automake.in: Here.
