title: What does vim wrap option actually do?
body: <p>I tried removing "set wrap" from my vimrc. I also set textwidth to 0. Still it wraps the lines  when it reaches window borders, i.e. no difference. So what does it actually do? I don't notice any difference after disabling it.</p>
  
  <p>Also I like the way textwidth works in the sense that it does not break based on window size. Is there a way to have vim do that, but visually (no real line break chars)?</p>
  
  <p>Thanks!</p>
