The flickering happens because the cursor briefly moves from the
minibuffer to the minibuffer selected window when the lazy highlighting
is done (e.g. after typing a character in the C-M-% regexp query).
The previous solution was to inhibit redisplay during that brief period.
The new and better solution is to just set cursor-in-echo-area, which
does exactly what we want to happen.
