pack-objects: improve returned information from write_one()
This function returns 0 when the current object couldn't be written due to the pack size limit, otherwise the current offset in the pack. There is a problem with this approach however, since current object could be a delta and its delta base might just have been written in the same write_one() call, but those successfully written objects are not accounted in the offset variable tracked by the caller. Currently this is not an issue but a subsequent patch will need this. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
