The only mention of this field in the code is by some debugging code which prints it out (and it will always be zero, since we never touch it otherwise). It was obsoleted very early on by 25d5ea41 ([PATCH] Redo rename/copy detection logic., 2005-05-24). Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
