Connectivity checks have to traverse the entire object graph in the worst case (e.g., a full clone or a full push). For large repositories like linux.git, this can take 30-60 seconds, during which time git may produce little or no output. Let's add the option of showing progress, which is taken care of by rev-list. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
