Also sometimes, long lines can more easily render the structure of the program. Like when a function is called with many/long arguments several times in a row, with varying arguments. If you have one line per call, you can easily see that it is the same function and what argument is changing at each call. If you rewrite each call as 5 lines, it is much more difficult to grasp what is going on. And when you need to change, say, the second parameter, you will see that the same call is made n times, and not forget one in the process.
