   6 # We want to create a situation where the shallow, grafted
   7 # view of reachability does not match reality in a way that
   8 # might cause us to send insufficient objects.
   9 #
  10 # We do this with a history that repeats a state, like:
  11 #
  12 #      A    --   B    --   C
  13 #    file=1    file=2    file=1
  14 #
  15 # and then create a shallow clone to the second commit, B.
  16 # In a non-shallow clone, that would mean we already have
  17 # the tree for A. But in a shallow one, we've grafted away
  18 # A, and fetching A to B requires that the other side send
  19 # us the tree for file=1.
