Thanks for your review!

I have tested ref count of reOle/txtDoc in Windows, and ref count
of reOle/txtDoc didn't increase after ITextDocument::Range. So I didn't
call AddRef in ITextDocument::Range.

  create_interfaces(&w, &reOle, &txtDoc, NULL);
  refcount = get_refcount((IUnknown *)txtDoc);
  ok(refcount == 3, "got wrong ref count: %d\n", refcount);
  hres = ITextDocument_Range(txtDoc, 0, 0, &txtRge);
  ok(hres == S_OK, "ITextDocument_Range fails 0x%x.\n", hres);
  refcount = get_refcount((IUnknown *)txtRge);
  ok(refcount == 1, "get wrong refcount: returned %d expected 1\n",
refcount);
  refcount = get_refcount((IUnknown *)txtDoc);
  ok(refcount == 3, "got wrong ref count: %d\n", refcount);
