Enable sub-processes to gracefully handle when the process dies by updating subprocess_read_status to return an error on EOF instead of dying. Update apply_multi_file_filter to take advantage of the revised subprocess_read_status. Signed-off-by: Ben Peart <benpeart@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
