Hmmm.... I think this may be the problem:

    % grep -r diff-filter Documentation/
    Documentation/git-diff.txt:$ git diff --diff-filter=MRC <1>

And that is:

    Limiting the diff output::
    +
    ------------
    $ git diff --diff-filter=MRC <1>
    $ git diff --name-status -r <2>
    $ git diff arch/i386 include/asm-i386 <3>
 
    <1> show only modification, rename and copy, but not addition
    nor deletion.
    <2> show only names and the nature of change, but not actual
    diff output.  --name-status disables usual patch generation
    which in turn also disables recursive behaviour, so without -r
    you would only see the directory name if there is a change in a
    file in a subdirectory.
    <3> limit diff output to named subtrees.

That's pretty thin documentation there. Unless someone beats me to it, I'll try to find a spare documentation cycle...
