diffcore-rename: record filepair for rename src
This will allow us to later skip unmodified entries added due to "-C -C". We might also want to do something similar to rename_dst side, but that would only be for the sake of symmetry and not necessary for this series. Signed-off-by: Junio C Hamano <gitster@pobox.com>
