Prefer snprintf to strncpy when outputting C strings

Browse Source 
strncpy is designed to output to fixed‐width buffers, not C strings
(hence its weird null termination behavior). In this case it happens to
work correctly due to the length check but, for style reasons, I would
rather use snprintf. Especially in this case, where it shortens the
code a bit.
