Package: mutt
Version: 1.5.13-1.1
Severity: normal

When displaying an index in threaded mode, the thread markers (for messages
nested in a thread) make lines wrap correctly. After some movement of the
highlight bar, the display becomes fairly unable without an explicit refresh
(^L).

I've reproduced this in several terminal emulators; (IIRC), iTerm on OS X,
PuTTY on Windows, and gnome-terminal under Linux. The "corruption after
highlight bar movement" is most profound when running mutt in a screen(1).

This only happens when LANG=en_US.UTF-8 (en_US.UTF-8.png, attached). If I
set LANG=en_US, the display is fine (en_US.png, attached).

FWIW, this seems similar to #328921 and #415277. I tried the latest mutt
from experimental, but the behavior is unchanged.
