Ah, I see now.  I think I know the feeling...

I just saw a diff fly by at the review emails at work, which replaced
strlcpy() with strncpy() because of a similar problem, only this time
the other way around.

The libc of BSD and Solaris includes strlcpy() and strlcat(), but it's
unavailable in Linux, so we have to either "hack around" the missing
feature with strncpy() or conditionally include a BSD licensed version
of strlcpy() to our compatibility cruft.

``Portability is a huge chimera.''  Oh well :(
