Hmm ... you are right that that code doesn't do what it seems to
intend to, because by the time that we get to this logic we have
i == 7 not i == 6.  But I'm not sure if we should change it after
all this time.  We're about as likely to get complaints as kudos,
I fear.  And the output isn't incorrect, just not-per-style.

I wonder whether ISC ever changed their version?
