Subject: [PATCH] Fix crash in mainwindows_resize_smaller when the
 'mainwindows' list is empty.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The crash can happen if the terminal height decreases before the first window
is created. Based on a patch by Jaroslav Škarvada (red hat bug #796457).
