OK, there doesn't seem to be much enthusiasm for putting this in our
precious mode line real estate, and I concur.

But I had another look at `describe-mode', and contrary to what I
believed, it does include stuff that's not directly mode-related.  In
particular:

        ;; Narrowing is not a minor mode, but its indicator is part of
        ;; mode-line-modes.
        (when (buffer-narrowed-p)
          (push '(narrow-to-region "Narrow" " Narrow") minor-modes))

So perhaps it'd be an idea to do the same with `lexical-binding'?
