The set of files or the set of Info nodes (which can appear in any file)
can't conveniently be treated as "a (short) list of strings".

I don't understand the question.  AFAIK it does work.  It just doesn't
return every possible node name, since there's pretty much an infinite
supply (if you include those that can be accessed via Tramp, for example).

>     (setq collection (funcall collection "" nil t))

Indeed (funcall collection "" pred t) should be equivalent to
(all-completions "" collection predicate) when `collection' is a function.
If you see otherwise, we have a problem.
