That is what we we usually call a regression, but I think the original is
not correct to begin with.  It should have used "$*" not "$@".

Make it a habit to always quote "$@" when relaying what was given to you,
so that when somebody sends a parameter with IFS in it, you won't split it
while passing it down. I.e.

	die () {
        	die_with_status 1 "$@"
	}

Blank line here after the closing brace and the beginning of next function.

I think an unconditional

	echo >&2 "$*"

is good enough here.
