(info "(elisp)Minor Mode Conventions")
[...]
The command should accept one optional argument. If the argument
is `nil', it should toggle the mode (turn it on if it is off, and
off if it is on). It should turn the mode on if the argument is a
positive integer, the symbol `t', or a list whose CAR is one of
those. It should turn the mode off if the argument is a negative
integer or zero, the symbol `-', or a list whose CAR is a
negative integer or zero. The meaning of other arguments is not
specified.
