This number of lines is specified by `window-min-height'.

We can add the MAX/MIN-HEIGHT/WIDTH arguments of `fit-window-to-buffer'
to the alist entries recognized by `display-buffer'.  Then
`minibuffer-completion-help' and friends could set them in a way we'd
have to choose yet.  Or we make these globally customizable.

I'm currently rewriting the code for *Completions* windows to make sure
they don't get obscured by an expanding minibuffer window.  If you have
a good proposal I can make the necessary changes right away.
