When attaching to an existing tmux session the panels order is different

[secsaba]

Starting tmux-cssh with the following command will result in this panel arrangement.

$ tmux-cssh c{1..6}

However if tmux is started and attaching the tmux-cssh with the -c option will result in a totally unordered panel arrangement.

$ tmux
$ tmux-cssh -c c{1..6}
