According to my V7 manual:

"Strncpy copies exactly n characters, truncating or null-padding s2; the
target may not be null-terminated if the length of s2 is n or more."
       ^^^ ^^^ ^^ ^^^^^^^^^^^^^^^

In other words, V7 won't guarantee which way it works, and if you want
to run on a V7 machine, you better not depend on any particular behavior.
