title: In vim, how to scroll, continuously, by screen lines when wrapping is enabled?
body: <p>I can get the bottom of the window to display partial lines by setting display=lastline</p>
  
  <p>Is there a similar option that would allow partial lines to be displayed at the top of a window?</p>
  
  <p>Without this functionality, my vim still scrolls (down) by more than 1 screen line when the topmost file line being displayed is wrapped into multiple screen lines.</p>
  
  <p>For example, in the following scenario, when I press C-E, my vim will scroll down by 3 screen lines. Is there a way to make it scroll by only 1 screen line such that only the first two words in line 1 are hidden, but the following 3 words are still displayed? This will be very useful for editing long paragraphs of text.</p>
  
  <p>Note: I'm referring to the scrolling of the entire screen, not the movement of cursor.</p>
