Just found a problem: sourcing the tmux configuration expands the
environment variables, too, and I don't see any way that allows
escaping. That means ':new-window -c "$PWD"' on the prompt works but
binding the same will resolve $PWD when parsing the config, not when
pressing the keys. Any recommendations how to solve this?
Did one of those "small cosmetic changes" in the last minute and
missed to remove the & in environ_find(&environ, ...). The attached
patch fixes that.
