Yea, it says both that it will never return a negative value (since size_t
is never negative) and that it returns the same things as snprintf (which
is true... except for that detail which it glosses over in return type
differences).

So this issue doesn't get lost, I've added a clarification to the examples
in  https://reviews.freebsd.org/D27228 . Please take a look and let me know
what you think. If more extensive edits are needed, there's full context so
you can at least flag those in the review as well. I've read these too many
times to see the other places you're talking about, so a fresh set of eyes
would be helpful.
