yes. this is correct and expected. you shouldn't attach a tmux session
inside itself or it'll go nuts if you try to switch the inside tmux to
the same window as the outer.

there was some changes at one point to make tmux detect if $TMUX was
invalid or not but i can't remember if they are in 1.3. maybe try CVS
HEAD but if it still does the same you'll just have to unset TMUX first.
