get-tar-commit-id: check write_in_full() return against 0
We ask to write 41 bytes and make sure that the return value is at least 41. This is the same "dangerous" pattern that was fixed in the prior commit (wherein a negative return value is promoted to unsigned), though it is not dangerous here because our "41" is a constant, not an unsigned variable. But we should convert it anyway to avoid modeling a dangerous construct. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
