But how?  What should the algorithm be?  Put a too long list of candidates 
in the minibuffer, redisplay, check if the resulting height is larger than 
then available height (with window-text-pixel-size?), if so remove a 
candidate, redisplay, ...?  Hmmm, no, you just wrote "without having to 
reduce the number of candidates inserted in the (mini)buffer", so it must 
be something else?
