    [nroff]: Update usage message.
    
    * src/roff/nroff/nroff.sh: Update usage message.  Present different
      modes of operation on separate output lines.  Revise metasyntactic
      variable names for clarity.
      - name -> string
      The former is not wrong but is too general.  In practice there is no
      way to populate a macro or diversion from a command-line argument.
      - reg -> register
      - expr -> numeric-expression
      Use complete words and the exact terminology from our documentation.
