I tend to disagree because I think of this as an interface to a (Lisp)
list, and because it makes customizing this variable slower than it
need be.  Can you say why having the "none" option works for you?

My point is that consistency is presumably a good thing, and if having
a choice of "none" is good for this list-that-might-be-empty, wouldn't
it be a better idea to have that built-in to the `repeat' widget?
