Hmh, good one. Didn't find an easy way to get to the bottom of this
within the ut test system, so I copied the ANSI sequences out and
replayed them with a custom command, inspecting the (sandbox) screen
manually. Is there a canonical way to trace down those issues?

Anyway, the fix for patch 2/8 is rather simple (see below), do you want
to fix this up in your tree? Or shall I sent a v2?
The head of my tree passes the video_ansi test now.

(This patch won't apply cleanly (blame Thunderbird), but I think you get
the idea...)
