"MUST BE POSITIVE" doesn't mean that a negative argument will
be rejected.  So the doc is perfectly allowed to say "MUST BE POSITIVE"
even if the code handles negative values (it just means that negative
values are "NOT SUPPORTED").  And if some core code uses negative
values, that's a naughty breach of abstraction, but that's about it.

So I see no bug here.  If you want a change, please say which and why.
