    Junio C Hamano authored
    Rename detection logic in "diff" family that is used in "merge" has
    learned to guess when all of x/a, x/b and x/c have moved to z/a,
    z/b and z/c, it is likely that x/d added in the meantime would also
    want to move to z/d by taking the hint that the entire directory
    'x' moved to 'z'.  A bug causing dirty files involved in a rename
    to be overwritten during merge has also been fixed as part of this
    work.  Incidentally, this also avoids updating a file in the
    working tree after a (non-trivial) merge whose result matches what
    our side originally had.
