Syntax:  VIEW SOURCE depth

  Displays the top levels of detail in the buffer.

  Lower levels of detail are collapsed and represented by overview
  lines.  LSE determines the relative level of detail of a line by
  comparing the indentation of the line with the indentation of other
  lines.  The treatment of the indentation of a line by LSE is
  influenced by indentation adjustment definitions.
