For Ediff's wide display feature I like to use my own
ediff-make-wide-display function. Ediff has a variable for this:
ediff-make-wide-display-function. However when I write:
(defun my-ediff-make-wide-display () ...) (setq ediff-make-wide-display-function #'my-ediff-make-wide-display)
my definition doesn't seem to get used when I toggle the display to wide view. I guess the reason is that
ediff-make-wide-display-function is defined as a local variable (via
ediff-defvar-local), and my
setq call sets the variable somewhere else...
So to which buffers is the definition local and how can I set it for all of these buffers?
