   *      Function name:  printremark ( string )
   *      Synopsis:       Print the given string as a series of "Remark" lines,
   *                      (i.e., preceded by backslash-space)
   *      
   *      Inputs:
   *          Parameters:     
   *              str     Pointer to the start of the string,
   *                      however long it may be.  The string
   *                      may have any number of embedded new-lines.
   *
   *      Outputs:
   *          Returned Value: *** NONE***
   *          Printout:    Each line of the string will be preceded by
   *                       a backslash and two spaces.  Backslash-space
   *                       is the standard delimiter for a "remark", i.e.
   *                       the entire line is ignored as a comment.  The
   *                       second space is "just" for aesthetics.
   *      
   *      Process Explanation:
   *          Parse the input string for new-lines.  Print each separately.
   *          Do not alter the input string.
   *      
   *
   *      Still to be done:
   *          Define a routine, call it  PrintComment , to print the given
   *              string surrounded by open-paren-space ... space-close-paren
   *          Define a single central routine, call it  safe_malloc ,
   *              to do the test for null and print "No Memory" and exit.
   *          Define a single central routine, call it  PrintError , to:
   *              Print the given error message
   *              Show the input file and line number
   *              Collect error-flags for failure-exit at end of operation.
