There's no "non-matchable space". The problem is rather that each key
(and each value) includes a trailing NUL byte, which happens to be
sendmails traditional database format for /etc/sendmail.db.

I happen to have some patches for that lying around, which adds an
"-z" flag to ypmatch. I haven't really gotten around to send them in,
so I guess this is a good time...
