That sounds surprising. Is this actually so?

    % () {
      typeset -L3 foo
      typeset -p foo
      unset foo
      typeset foo
      typeset -p foo
    }

    typeset -L3 foo=''
    typeset foo=''

Here unset + typeset removed justification, as I would expect. Am I
misunderstanding what you meant?
