Socket Server hint

Oh, hm. We'd better treat this "hint" as a bugreport. I'm very sorry, there remained a small inconsistency after some initial versions of the "client" which tests the server... Fixed now, hopefully. I myself used substring search as you suggest in order to save myself from line endings etc - so missed the issue.

And thanks for your efforts in testing this mini-monster.

This problem has been such a struggle for me. I hope there will be more tasks of this type in the future though. I really liked that one.
