Uh, backwards. "$@" is how you pass an unmolested argument list.
(Except with some rather old Bourne shell implementations, where you
have to use ${1+"$@"} to avoid turning an empty argument list into an
argument list with one empty word. But nobody worries about that any

You'll note that "$*" smashed the four arguments into one word, while
"$@" kept them as three words.
