My 23.2 code shows all-completions accepts 4 args.
Heck, even the 24 branch still accepts 4 args.

It doesn't have its place in `all-completions' (which is an internal
function, and hence not directly related to any UI feature).

You can get the same result by changing the completion table instead, or
by changing the `predicate'.  These approaches also have the advantage
of being a lot more flexible.
