So far as I can tell, this is perfectly standard.  I'm looking at the
man pages for strncpy from Ultrix (DEC Unix for VAX) and Sun OS 4.0
and both warn that strncpy can produce unterminated strings.  Sorry, I
don't have the Think C libraries manual here, but I'd be amazed if it
says anything different.
