[PATCH v2 0/3] Protocol v2 in_vain fixes

I'm not sure if Jonathan Nieder meant the enum-from-process_acks() change should be in this patch set, but I've included it here anyway. Also I've removed an extraneous debug "cp" from patch 2/3 (previously patch 1/2).

Jonathan Tan (3):
  fetch-pack: return enum from process_acks()
  fetch-pack: in protocol v2, in_vain only after ACK
  fetch-pack: in protocol v2, reset in_vain upon ACK
