Yes, I thought you meant that.

Thanks for the example. That way it works.

I think I understand how it is implemented now, but it has unnecessary
restrictions. Suppose you do M-x org-insert-link before you store any
link. Then you do not get any way to add a link to the nodes in the
current file or any other file. I think the code to do this is nearly
there, but ...

(info "(org) Internal links") says:

   To insert a link targeting a headline, in-buffer completion can be
   used.  Just type a star followed by a few optional letters into the
  buffer and press `M-<TAB>'.

That does not work for me. You can surely do in buffer completion (but
I do not know why this is useful here), but a link is not inserted.
How do you actually do it from that point?

May I suggest using more normal completion? Then for example Company
Mode can be used... - it can handle many completions nicely so having
candidates from a set of files is not a problem...
