display: restore the ability to resize the screen while searching

This ability was lost in commit 92298349 from two hours ago, which
bypasses the keystroke buffer and its integrated screen resizing.

This new implementation is better than it was before, because it
responds almost instantly to a resize instead of with a delay of
up to a second.
