Current version:

--8<---------------cut here---------------start------------->8---
     (setq-default mode-line-format
                      (let ((dict (and (featurep 'ispell)

                                       (or ispell-local-dictionary
                        (and dict
                             (propertize (concat " [" (substring dict 0 2) "]")
                                         'face 'mode-line-highlight))))
                    (default-value 'mode-line-format)))

I'd prefer to always (when it makes sense) see the current dict, with the same
argument as the one you just used: like the input method, we want to always see
the current one in the mode line.
