hrm.
diff(1) doesn't seem to know how to handle a zero-length file.
y:/home/akpm> mkdir foo
y:/home/akpm> cd foo
y:/home/akpm/foo> touch x
y:/home/akpm/foo> diff -uN x y

So when comparing a zero-length file with a non-existent file, diff
produces no output.
This'll make things happy. And I guess it should be done to protect
all the valuable intellectual property in that file.
