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