  Moves the cursor a paragraph at a time in the reverse direction.
  Steps:

  Usage notes:
  O  Prev Paragraph always moves to the start of the current or the previous
     paragraph, if any.
  O  Paragraph boundaries are any of the following:
        *  Blank line
        *  Top or bottom of the buffer
        *  Page break (form feed at the start of a line)
        *  RUNOFF command (such as .BREAK;) at the start of a line
        *  VAX DOCUMENT tag (such as <LE>) at the start of a line
  O  If there is no blank line or other paragraph boundary in the reverse
     direction, Prev Paragraph moves to the top of the buffer.
  O  To reformat the current paragraph, use the FILL command (with the WPS
     keypad, press GOLD-KP5).
  O  With the WPS keypad, CTRL/UP continues a case change as follows:
     1.  Press the WPS Lower Case key (GOLD-KP3) or WPS Upper Case
         key (KP3) to change the case of the current character.
     2.  Press CTRL/UP to continue the case change to the start of the
         previous paragraph.
