I am not sure "work fine" a fair and correct label, as rename is
always heuristic.  

    The "directory rename detection" heuristic in "merge" and the
    "interactive" backends can take what happened to paths in the
    same directory into account when deciding if a disappeared path
    was "renamed" and to which other path.  The heuristic produces
    incorrect result when the information given is only about
    changed paths, which is why it is disabled when using the "am"
