It doesn't take more than two dozen or so lines depending on the window arrangement. Nothing truly excessive. Alternatively, viewing the entire code block might mean scrolling up. If you want scary, check out GNU's implementation of `cat`. I think they hit ten nested indentation levels. Though, because that's C, you can at least jump between the beginning and end of each level by having your editor jump to the matching {}.
