Well, it needs to handle the case where a patch simply and only renames
a file.

Then, even if a patch follows:

diff --git a/README b/README.old
similarity index 99%
rename from README
rename to README.old
index a24ec89ba442..b0a7aa56c3cc 100644

         Linux kernel release 3.x <http://kernel.org/>
 
 These are the release notes for Linux version 3.  Read them carefully,

it says:

$ git diff --cached HEAD -- | ./scripts/checkpatch.pl --strict -
Must be run from the top-level dir. of a kernel tree

If I comment out the following hunk:

        if (!defined $root) { 
                print "Must be run from the top-level dir. of a kernel tree\n";
                exit(2);
        }

then it works, albeit with a bunch of warnings:

CHECK: Patch renames README to README.old, update MAINTAINERS?

Looks like this would need a bit more work.

Thanks.
