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.
