I had the same problem: it appeared in Emacs master recently.

Right, as I said, this is to show you how eldoc-display-function works,
not to fix your library definitely. Anyway, in the
eldoc-tooltip-joao.el file I gave you, I passed the function #'car to
mapconcat, right? This was just a quick and lazy solution: to get that
augmented information you have to pass it a function that uses more
properties of the list that represent a piece of documentation. But I
think the previous 'martin' function I gave you should have exactly that
string producing function inside it, right?

Makes perfect sense I guess. You should be able to
(remove-hook 'eldoc-display-functions 'eldoc-display-in-echo-area)
If you're not a fan of the echo area display.

Yes, it is. But do you really need a minor mode? I think activating
your extension could be a matter of:
(remove-hook 'eldoc-display-functions 'eldoc-display-in-martins-tooltip)
instead of a global minor mode. Then you would let ElDoc mode _drive_
your extension.
