title: Auto-commenting on newline, SublimeText
body: <p>Could someone point me how to make SublimeText insert comment continuation double-slashes when I enter a new line while inside a comment block?</p>
  
  <pre><code>// I have comments like this, and when I enter a '\n'
  // it break's out of comment-entering mode 
  like this (drops slashes, cursor stays at leftmost column)
  
  // and I want to have them automatically inserted after hiting '\n'
  // like this
  </code></pre>
  
  <p>I might have changed that on accident while tweaking preference file, and I don't know how to set it back.</p>
  
  <p>here is my user <strong>prefs</strong>:</p>
