Subject: [PATCH] tmux: Fix scrolling down in alternate mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Scrolling down with the mouse wheel in alternate mode (e.g. less)
stopped working for me. I'm pretty sure that this used to work, but tmux
never had a default binding for WheelDownPane, so I'm unsure from where
this change should have come from ¯\_(ツ)_/¯
