/UNIT
       /NOUNIT (D)

    Treats consecutive lines as a single unit. If consecutive lines in
    the buffer match adjustments defined with the /UNIT qualifier and
    have the same adjusted indentation, then the sequence of lines is
    treated as one group, with the first serving as the overview line.
    Notice that it is not required that all elements of the group
    match the same adjustment definition; it is only required that the
    /UNIT qualifier be specified on all the definitions.
