No, it doesn't. No existing prototypes are changed, there are just a
number of *nvis* functions added to complement the existing ones that
didn't have length arguments. The only problem is that the port assumes
that if a system has strnvis, it has a prototype matching OpenBSD's,
which the new one doesn't.
