Consider the case where you have trunk, branchA of trunk, and branchB of
branchA. trunk is merged back into branchB, and then branchB is
reintegrated into trunk. The merge of branchB into trunk will have
svn:mergeinfo property references to both branchA and branchB. When
performing the check_cherry_pick check on branchB, it is necessary to
eliminate the merged contents of branchA as well as branchB, or else the
merge will be incorrectly ignored as a cherry-pick.
