[...]
Sometimes using the braces would "look odd" to experienced shell
folks, and are omitted by convention:

    echo $1 $2 $3              # looks "odd"
                                          ^^^
s/odd/normal/

    echo "$1" "$2" "$3"        # same here, and safer in general

    echo ${1} ${2} ${3}        # looks "odd"

    echo "${1}" "${2}" "${3}"  # ditto
[...]
