Right, but restoring the old behaviour for white spaces only is
silly. It's silly
to have this work:
set -- A1 B2 C3
echo ${@%2 C3}
but not this:
set -- A1 B2 C3
IFS=:
echo ${@%2:C3}
Of course, in the old dash both worked which makes more sense.
But that was at the cost of not eliminating empty fields which
violates POSIX.
Cheers,
