Seems very complex for just returning a (short) list of strings.
Why doesn't this work for `Info-read-node-name-1':

    (setq collection (all-completions "" collection predicate))

while this works within the topic, but not in the directory:

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

If I understood the info page correctly, both should be equivalent.
