The variable has a docstring. This is the crucial source for you.
Nearly all mode variables are interpreted as Bools in Emacs.
The argument of the mode functions is different because it is often also
the prefix arg, which is a number (not even only just that, actually).
But it can also be called from Elisp. That's why its semantics are a
bit ugly.
Michael.
