Subject: [PATCH] Demonstrate that toggling whitespace undims the panel beneath
 the main view
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Toggling whitespace re-focuses the side panel to re-render the diff, which
also re-derives that panel's highlight — as though the panel had the focus,
which it doesn't.
