In a pipe, only the return code of the last command is used. Thus, all other commands will have their return codes masked. Rewrite pipes so that there are no git commands upstream so that we will know if a command fails. Signed-off-by: Denton Liu <liu.denton@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
