In git.git history, "git-whatchanged -m -p -1" gives different output for
the following commits, with and without the patch:

        c0e9892637e8144f10f2c408e276a470520f3601
        d6b3e3a33f71910526ccf80af6c13a230363cd89
        cecb98a9c3ed9271b0974bb6d7edbcf16e8a68f3
        ce18135d862b5dbc731d203b27c279529e58b54b
        36b5b3c65948694d9a92de5a17f2b97c3cd84879
        767e130915015f897fb87b939843b4882212574b
        927a503cd07718ea0f700052043f383253904a56

I've sampled a few (but not all) of them and they are different only
because just how common lines are matched up, which is expected.
