Bug#731738: apt: fancy progress breaks “show the differences between the versions”

[Thorsten Glaser <tg@mirbsd.de>]

Package: apt
Version: 0.9.14
Severity: normal

Hi,

I’ve got lengthy local deltas in /etc/lynx-cur/lynx.cfg and was
just prompted by dpkg how to handle it, while the fancy progress
thing was still visible. I told it to show me the diff (in less),
and the progress thing vanished, but after scrolling down then up
then down then up, I could not scroll in at least one direction
any more. This is reproducible.
