The concat() method is weird in that if the arg is empty, it requires returning 'this'; but if 'this' is empty, it requires creating a new String instead of just returning the arg.

Woops, I forgot, I did change the concat() spec to no longer require creating a new string in the case where 'this' is empty. I think it's still overspecified, in that it requires returning 'this' if the arg is empty, though this doesn't seem to do much harm.
