I was checking that add_filer_to_cache() did not inadvertently use these
global variables even after the refactoring, and it looks good. It's a
pity that we can't remove the USE_THE_INDEX_VARIABLE #define even after
this patch (other parts in builtin/add.c use it), but I couldn't see
any more usages of the_index in that function. There is no more usage
of include_sparse, indeed, as can be seen from the next patch (when the
function is moved to another file that has no access to include_sparse
declared in builtin/add.c).
