Subject: Nuke the utf8 and status-utf8 options and make tmux only a UTF-8
 terminal. We still support non-UTF-8 terminals outside tmux, but inside it is
 always UTF-8 (as when the utf8 and status-utf8 options were on).

Subject: tmux is UTF-8, so if $TMUX is set (tmux running in tmux), the client
 is UTF-8. Also try to make the existing checks more readable.
