>Description:
Weird things when using tmux(1) and vim(1) inside:

if TEKEN is cons25, we lost DEL (got second backspace)
if TEKEN is xterm, we got weird tmux behaviour (window with vim(1) will be splitted)
>How-To-Repeat:
I've builded up my freebsd box, and teken is setted to cons25 by default (kernel uses UTF-8 teken with config)

when I start tmux and vim nested, I'll have no problems, except DEL key is binded as backspace.(this is weird)

example:
$ vidcontrol -T cons25 && tmux
and inside tmux:
$ vim /etc/rc.conf 

When I set TEKEN to xterm (vidcontrol -T xterm), I'll get serious problems with windows inside tmux:
$ vidcontrol -T xterm && tmux
and inside tmux:
$ vim /etc/rc.conf 

we got working DEL character in vim(1), but when we do something with tmux (create new window, for example) or exititng vim(1), window with vim will be splitted.


PS: I have zsh with 2-lines PS1 as work shell.
