bug#17644: 24.4.50; provide access to all mode-line lighters (e.g. those


From: Drew Adams
Subject: bug#17644: 24.4.50; provide access to all mode-line lighters (e.g. those from C code)
Date: Fri, 30 May 2014 08:34:27 -0700 (PDT)

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.
