docs: Set the options for 'command_obj' from 'option_dict'.  Basically
          this means copying elements of a dictionary ('option_dict') to
          attributes of an instance ('command').
  
          'command_obj' must be a Command instance.  If 'option_dict' is not
          supplied, uses the standard option dictionary for this command
          (from 'self.command_options').
