title: Pylint: Disable Unnecessary "else" after "return" (no-else-return) warning
body: <p>I'm looking through my RC file and I can't for the life of me, find which one of these variables disables that feature. </p>
  
  <p>I searched for "if", "else" and "return" and I didn't see anything. Unless I've missed it.</p>
  
  <p>Thanks.</p>
