Syntax:  SET ADJUSTMENT UNIT boolean defined_adjustment
              defined_language

  Tells LSE to treat consecutive lines as a single unit.

  If consecutive lines in a buffer match adjustments defined in this
  command and have the same indentation, then the sequence of lines is
  treated as one group with the first line serving as an overview line.
  Note that all the lines do not have to match the same adjustment
  definition; you only need to use this command on all definitions.
