kak_client_env_TMUX erroring out when calling fzf-ctags #91

This line causes problems for me (sh: 36: kak_client_env_TMUX: parameter not set or null). Changing ${kak_client_env_TMUX:?} to ${kak_client_env_TMUX} fixes the problem. What's the meaning of the :? here?

oops, you right, I only use kakoune from tmux, so I've forgot that this variable can be empty for others.

:? forces the runtime check that variable is set
