If the message said "we will be changing the default in the future, so this is to warn people who want to keep the current default what to do", it would have made some sense, but as it stands, the message is merely an unsolicited advertisement for a new feature, which it is not helpful at all. Squelch it. Signed-off-by: Junio C Hamano <gitster@pobox.com>
