But what if the same persion notices a #define in a kdeutils header file
and want's to know whether it is unused in order to remove it:

    $ git grep FOO
    kdeutils/foo.h:#define FOO bar

Conclusion from this output: "It's only defined, but not used anywhere."
But this conclusion is not necessarily correct because FOO could be used
outside kdeutils.

So, no, "git grep" should disregard the checkout area.
