My proxy tends to block every patch after a batch of 4 or 5 patches. Since it splitted the serie in half I resent it so that the serie could be entirely read without problems. This explains the resend. I was not sure about putting a short explanation in the cover letter since it was not related any change in the serie, but next time I will do so.
