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