title: vim line operations (e.g., dd) on wrapped text
body: <p>I'm using wrap in vim, but I want vim to otherwise behave as though the lines have actual breaks in them (rather than "soft breaks" for screen rendering).</p>
  
  <p>I've mapped j to gj and k to gk for navigation. However, line operations (such as dd) still act upon the whole line, rather than the "screen line". Is there any way to alter this behavior such that 'dd' is limited to the screen line?</p>
