Is there any reason for uses like this one from simple.el:

  (error (format "No further undo information%s"
               (if (and transient-mark-mode mark-active)
                   " for region" "")))

instead of simply:

  (error "No further undo information%s"
         (if (and transient-mark-mode mark-active)
             " for region" ""))
