Syntax:  FILL column

  Reformats the text within a selected range.

  The FILL command reformats a block of text or program comments in
  order that as many words as possible fit on each line without
  exceeding the right margin.  Reformatted text is indented to the left
  margin for the buffer.  Comments are indented to the column specified
  or the current column if none is specified.  LSE treats the spaces
  defined placeholders as whole words.

  If you do not provide a selected range, this command reformats the
  current paragraph.  The current paragraph includes the text on all
  previous and subsequent lines until LSE encounters a completely blank
  line.  LSE preserves any blank lines in the text.

  If the buffer is associated with a language, and comment delimiters
  have been defined for the language, LSE reformats the commented
  segments of the lines in the selected range.  If the buffer is not
  associated with a language, or there are no comment delimiters, LSE
  performs a text fill.
