The problem is the arguments are reevaluated after they are assembled
by the function (or shell script).  $* dosn't group them.  That is why
you have all seperate arguments (the "'s are gone when they are
reevaluated).  "$*" will expand as "$1 $2 $3".  This also is not what
you want.  "$@" will expand as "$1" "$2" "$3".  This *IS* what you want:

	tst()
	{
		echo '"$@"'
		for i in "$@"
		do
			echo "-> $i"
		done

		echo '"$*"'
		for i in "$*"
		do
			echo "-> $i"
		done

		echo '$*'
		for i in "$*"
		do
			echo "-> $i"
		done
	}

	$ tst "a b c" d
	"$@"
	-> a b c
	-> d
	"$*"
	-> a b c d
	$*
	-> a
	-> b
	-> c
	-> d
