That way we don't have to worry about > inadvertently affecting other users of the mini-window. It might be difficult/inconvenient to have the info directly in the text, tho. Having it in a variable is not great (one of the problems with it is that it depends on things like point so it's really more "per-window" whereas variables are "per-buffer"), tho for the case of minibuffers at least those buffers are normally never shown in more than one window. How 'bout using a window-parameter whose value should be an overlay indicating the "area of focus", and then only obey this parameter if: - the overlay is in the buffer that's being displayed. - and window-point is lies within this overlay. One more thing: there's a good argument to make that icomplete-vertical should list the completions *above* the minibuffer's prompt rather than below (so as not to affect the positions of the minibuffer's prompt so much). But in that case, the part of the overlay's after/before string (when too long) which should be truncated (when the mini-window is too small) is the beginning, whereas IIUC the current redisplay is unable to display "the end" of an overlay's after/before string unless it also shows its beginning.
