I don't understand why you keep saying this.  Without the braces
your command would be completely different.  This:

    [ "${${1}##*[*?]*}" ] &&
    echo "no wildcards"; printenv "$1" ||
    echo wildcards present

is equivalent to this:

    [ "${${1}##*[*?]*}" ] && echo "no wildcards"
    printenv "$1" || echo wildcards present

which is not at all what you want.
