Bug #6732: documentation error in IPSocket#peeraddr

ri1.9.3 IPSocket#peeraddr
says
  TCPSocket.open("www.ruby-lang.org", 80) {|sock|
    p sock.peeraddr #=> ["AF_INET", 80, "carbon.ruby-lang.org", "221.186.184.68"]
    p sock.peeraddr(true)  #=> ["AF_INET", 80, "221.186.184.68", "221.186.184.68"]
    p sock.peeraddr(false) #=> ["AF_INET", 80, "221.186.184.68", "221.186.184.68"]
    p sock.peeraddr(:hostname) #=> ["AF_INET", 80, "carbon.ruby-lang.org", "221.186.184.68"]
    p sock.peeraddr(:numeric)  #=> ["AF_INET", 80, "221.186.184.68", "221.186.184.68"]
  }
the third line is wrong: peeraddr(true) actually returns the same as peeraddr(:hostname)
