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.
