It doesn't say what happens if ARG is zero, so perhaps the last sentence above should be amended to say "negative number or zero".
By the law of trichotomy, every real number is either positive, negative, or zero. Thus, if a real number is not positive, it must be either negative or zero. It follows that it suffices to say:
"If called from Lisp, toggle the mode if ARG is ‘toggle’. Enable the mode if ARG is nil, omitted, or is a positive number. Disable the mode otherwise."
Clear and precise. R+ --Programming reliably --- must be an activity of an undeniably mathematical nature [...] You see, mathematics is about thinking, and doing mathematics is always trying to think as well as possible. -- Edsger W.
