That's indeed similar to what the external package does with some extras
(remove the {} and add the extra line after the {, truncate the long
ones, resize automatically when less candidates based on an option).

Then the only thin we need is (setq resize-mini-windows nil) and doesn't
need to be in the icomplete-minibuffer-setup-hook.

The problem was that I tried to avoid calling enlarge-window and I
thought there was a good reason to do that... my bad.
