This just works:

(setq display-buffer-alist '(("^\\*Completions\\*$" .
                              (display-buffer-at-bottom
                               (window-height . 10)))))

For the simplest case this works... But there is not a way to handle the
conditionals without affecting some users. For example when using inline
completion or the ones using resize-temp-buffer-window

We can use a function instead, but in that case the user customization
may need a more complex approach instead of just a setq.

Maybe a better lisper could propose something better that allows to set
this without a defun, an advise or defining a tricky alist that may
conflict with something else?
