Add option to overwrite the is_vim command.

[Feferoni]

Would be great if you could add the option to be able to overwrite the is_vim command so that other programs than vim/nvim could be included.

Because when I use fzf for different things in the terminal, I want to be able to navigate up/down with the ctrl + k / j.

Solved it with:
is_vim="ps -o state= -o comm= -t '#{pane_tty}' | grep -iqE '^[^TXZ ]+ +(\\S+\\/)?(g?\.?(view|n?vim?x?)(-wrapped)?(diff)?$|fzf)$'"

But would be great to be able to set this from the .tmux.conf.
