commit 355f78364a7d1fa3c2de0a93e68153ae65526e02
Author: teor (Tim Wilson-Brown) <teor2345@xxxxxxxxx>
Date:   Thu Mar 24 20:59:49 2016 +1100

    Clarify ReachableAddress log messages
    
    Make it clearer that they are about outgoing connection attempts.
    Specify the options involved where they were missing from one log
    message.
    Clarify a comment.
