'S' in %pIS is for Sockaddr, since this patch makes it accept union
inet_addr instead of struct sockaddr, I don't think 'S' is meaningful
any more.

The "%pIS" change exists in v1, I don't know why you think it is new in
v2. Also, if you can point all what you dislike at one time, it would
save time for both of us, I prefer to fix them all in one update.
