It's not yet ready for broader discussion. I attach it here so you
can just test whether making the echo interference go away during
the minibuffer dialog.
To put it into use run emacs with
(setq default-frame-alist '((minibuffer . loose) (echo-area . t)))
Looks better with window dividers enabled.
Eventually I'll make a remote branch. But this may take its time.
