`indicate-empty-lines' is already a defcustomed variable (actually set
in startup.el). `indicate-buffer-boundaries' is not, but it should be
and the patches below make it customizable through startup.el.
That sounds like a good idea. Your change in cus-start.el is a good one
(assuming the details are right--I will take your word for that).
Once
this is done, there is no longer any need for the annoying
fringe-indicators variable.
The reason for this is to make it simple to request the usual options.
This is the right thing for the menu bar.
But I agree it shouldn't get in the way of setting the other variables
directly, if you want to do that. So I propose this change.
(I will also change the doc strings of default-indicate-empty-lines
and default-indicate-buffer-boundaries.)
