Alas, according to my copy of SystemV Interface Definition, strncpy:
"... copies exactly n characters, truncating s2 or adding null characters
to s1 if necessary.  The reult will *not* [my emphasis added] be null-
terminated if the length of s2 is n or more."  Since Minix is based
upon Version 7, the adherence to this "standard" is expected.
