Elisp users can modify mode-line lighters for a major or a minor mode,
using `mode-name' and `minor-mode-alist'. But they cannot modify (or
even remove) other lighters that are added by Emacs C code. Please
enhance Emacs by making this possible (from Lisp).
For example, when the buffer is narrowed, the lighter `Narrow' appears.
It is neither a major-mode lighter nor a minor-mode lighter. And there
is no way for a programmer to modify it from Lisp.
Please (a) document all such abnormal/extraneous lighters together,
somewhere in the Elisp manual and (b) provide a means for users to
access and modify them using Lisp.

Just replace %n with your own implementation.
Andreas.

"%n"

:test 'string=

Good; thx. I didn't realize there was a separate % construct
just for `Narrow'.
Is `Narrow' the only such "abnormal" lighter implemented in C?
If so then I will close this bug. Thx.

Actually, no. I would also like to be able to keep `%n' and its
behavior, and use alternative text instead of " Narrow".

I think you can just create a new one that has the same behaviour and a
new text? So I don't think there's anything to fix here.
