Entries should end with a period (not the title, though). Also, if you
haven't signed FSF papers yet, you should append "TINYCHANGE" on a line
on its own.

This should be (delq nil all-links).

I don't see the interest of this change nor how it is related to
allowing ido usage to insert links. Can

  (append
    (mapcar (lambda (x) (list (concat x ":"))) all-prefixes)
            (mapcar 'car org-stored-links)
            (mapcar 'cadr org-stored-links))

contain nil values?

If so, adding a (delq nil (append ...)) should be enough. This should be
a separate patch anyway.

Ok. There are a couple of places where this could be used
(`org-file-complete-link' for example). You should describe ARGS in the
docstring, though (writing, at least, that they refer to arguments from
`read-file-name').

Also, I'm not sure about the name. `completing-read' became
`org-icompleting-read'. Shouldn't `read-file-name' become
`org-iread-file-name'?
