OT: snprintf() null termination

[Vanja Hrustic <vanja () vanja com>]

I remember there were threads about this issue already, but it's hard to
draw a conclusion.

So - do all platforms properly null-terminate string (on overflow) when
snprintf() is used, or one should still use "sizeof(string)-1" for the
size of the snprintf()-ed string?

Thanks.
