tmux would not accept an option name or value.

Classified because the three answers call for different fixes: an
unknown name is a typo, an ambiguous one needs more of the name, and a
rejected value needs a different value. A caller reading stderr would
have to know that tmux says "bad value" for a flag and "value is
invalid" for a number.
