IMHO, this is a bad idea. The intention of add-to-list is to add
something to whatever the value was before, right? And before the
add-to-list, the most meaningful value would be the default value
(instead of nil).
Now, if a variable has a non-nil default value, then your suggestion
means it will have a very short value: just the single item you put
in it. So
(defvar foo)
(add-to-list 'foo 'item)
could as well have been written
(setq foo '(item))
Now, most lists should have nil default values, to facilitate
Customize. But your argument strikes me as a bad argument: to add
something to the default value, users will have to require the
corresponding *.el file anyway.
Or am I misunderstanding something here and way too tired?
