I reread the man page, and I agree that +nomultiline is not what I
want. The head suggestion won't work, because in the above example,
it is the second line I want.

Failing a better suggestion, I'll just have to parse the output.
Perhaps I will test each line with inet_aton until I get one that
works.  I was hoping to avoid that.
