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,
