After defining a minor mode with

(define-minor-mode foo-mode nil)

its docstring will be

"Toggle Foo mode on or off.
With a prefix argument ARG, enable Foo mode if ARG is
positive, and disable it otherwise.  If called from Lisp, enable
the mode if ARG is omitted or nil, and toggle it if ARG is ‘toggle’."

This appears to indicate that

(foo-mode 'banana)

should disable foo-mode, but it enables it.  I think minor modes should
simply not allow anything but integers and 'toggle for ARG, avoiding
this confusion.
