title: setting default syntax for sublime doesn't work
body: <p>Whenever I open a .m file the default syntax is objective-c but I want to change that to matlab. So when I open a .m file I go to </p>
  
  <blockquote>
    <p>view -> syntax -> open all with current extension as..</p>
  </blockquote>
  
  <p>and choose matlab. After that if I open another .m file the default syntax is matlab. But if I close sublime and open it again the default syntax is back to objective-c.</p>
  
  <p>I added objective-c to ignore syntax list but now it opens .m files as plain text. Is there another way to set default syntax for a file extension?</p>
