Well, I generally make sure the array I'm copying INTO is larger than
what I'm copying.  That way the null terminator gets copied in as well
and everything is cool.

I could make the argument that it's poor programming practice to be
copying strings into arrays that aren't large enough to hold them, and
that strncpy() is merely making the best of a bad situation.  You could
probably counter with an excellent example of a real-life instance where
the situation arises.  I would then counter that if you're doing things 
that are that sophisticated, it's a good time to write your own function
that works just like strncpy(), but that does string termination the
way you want it to be done!

Personally, I think strncpy() works just fine as is.  As I said, I
have never had a situation where I needed it to do anything other
than what it does.
