My problem was that with TERM=xterm-256color inside tmux, mutt would
draw rows at the wrong place as you scrolled through the message list.
However, I first observed this behaviour with tmux 0.8; it doesn't seem
to be a problem with 1.0.

tmux isn't quite compatible with TERM=xterm-256color, though. xterm
implements 'background color erase', which means that the following
command paints the entire terminal green:

    tput setab 2; tput clear

tmux doesn't support 'background color erase', which means that the
above command results in a terminal in the default colours.

This shows up in mutt in the very first line, where keyboard shortcuts
are displayed - if this line has a background colour, and
TERM=xterm-256color (or any color xterm variant) the background colour
extends all the way across the window in screen and gnome-terminal,
while in tmux the background-color stops at the right-most text on the
line.
