title: Git: fatal: Cannot lstat '.README.swp': Permission denied
body: <p>Seems, that I created by mistake a file .README.swp. (actually, by using command <code>vim README</code>). 
  So, now I have: </p>
  
  <pre><code>$ git status
  On branch master
  Untracked files:
    (use "git add &lt;file&gt;..." to include in what will be committed)
  
          .README.swp
  
  nothing added to commit but untracked files present (use "git add" to track)
  </code></pre>
  
  <p>When I'm trying to use command: <code>git clean -f</code> I have the following message:
  fatal: Cannot lstat '.README.swp': Permission denied</p>
  
  <p>How can I delete it then?
  Thanks in advance!</p>
