title: Weirdness when saving a new file with Sublime Text 2, it creates an extra file
body: <p>Every time I save new file created within Sublime Text 2 I get an extra file with hex numbers in it.</p>
  <p>Example:</p>
  <blockquote>
  <p>C + N (new file)</p>
  <p>C + S (save file)</p>
  <p>I save it as: &quot;test.rb&quot;</p>
  <p>Now I have: &quot;test.rb&quot; and &quot;._test.rb&quot;</p>
  </blockquote>
  <p>Why? What is the extra file full of hex numbers? How can I prevent this?</p>
