title: liclipse theme and mysterious line in the middle
body: <p>I installed LiClipse and Darktheme, there's a weird vertical line in the middle of the source code window I can't get rid off.</p>
  
  <p>Infact, eclipse with pydev and theme applied also had this mysterious line, what is this used for and how do I mute it?</p>
