From bcbfee8ff8bf115ace00870560f1a2240d612413 Mon Sep 17 00:00:00 2001
From: Iain Patterson <me@iain.cx>
Date: Mon, 14 Jan 2008 22:34:05 +0000
Subject: [PATCH] Forget the number mode stuff.  It doesn't work. Use Qn to
 toggle number. Use Q> and Q< to resize the window. Moved compatible mappings
 to Vim 5 section.
