That docstring, and all the others describing minor mode
(de)activation commands are somewhat ambiguous to me, because, as in
math literature, "positive" could or not include the number '0',
depending on author's definition.  However, "strictly positive" always
excludes zero, while "non-negative" always includes it.  So, I think
the latter would be a more appropriate term, instead of simply
"positive". 

Ps: Emacs developers, please, take this as a bug report ;-).
