The time-honoured way to achieve this is using the built-in `set'.

    $ l='foo bar xyzzy'
    $ set -- $l; for f; do echo f=$f; done | fmt
    f=foo f=bar f=xyzzy
    $ 
    $ l='foo bar'
    $ set -- $l; for f; do echo f=$f; done | fmt
    f=foo f=bar
    $ 
    $ l='foo'
    $ set -- $l; for f; do echo f=$f; done | fmt
    f=foo
    $ 
    $ l=
    $ set -- $l; for f; do echo f=$f; done | fmt
    $ set -- $l; for f; do echo f=$f; done | wc -c
    0
    $
