simple!  Here's the revised script:

options=
while [ "$#" -gt 0 ]
do
	case "$1" in
	--)
		shift
		break
		;;
	-*)
		options="$options $1"
		shift
		;;
	*)
		break
		;;
	esac
done
IFS=":$IFS"
case "$#" in
0)
        echo >&2 "usage: $0 file [path ... ]"
        exit 1
        ;;
1)
        file="$1"
        shift
        for d in $PATH
        do
                if [ -s $d/$file ]
                then
                        /bin/ls$options $d/$file
                        exit 0
                fi
        done
        ;;
*)
        file="$1"
        shift
        for d in $*
        do
                if [ -s $d/$file ]
                then
                        /bin/ls$options $d/$file
                        exit 0
                fi
        done
        ;;
esac
echo >&2 "$0: $file not found"
exit 1
