title: opening file with vim creates a new file although the file exists
body: <p>I am trying to read the apache error log in <code>var/log</code>. I have an <code>error.log</code> file there, but when I <code>sudo vim</code> it a new <code>error.log</code> file is created. I'm pretty sure there should be something in there as I'm trying to debug a 500 internal server error.</p>
  
  <p>Thanks for your help!</p>
