title: Strange git branch showing up in all my repos
body: <p>I noticed that any git repo that I create or clone has a <code>—quiet</code> branch in it,<br>
  I cannot check it out or do anything with it and I don't know where it comes from,<br>
  Any ideas? </p>
  
  <p>I regularly use github, source tree (mac version), git command line,  </p>
  
  <p>Any suggestions is appreciated,  </p>
  
  <p><b>EDIT2:</b><br>
  as noted by @DCoder the first character is not a regular hyphen or minus sign, which makes it even more suspicious, </p>
  
  <p><b>EDIT:</b><br>
  If I do <code>git branch</code><br>
  I get:  </p>
  
  <pre><code> * ali
    master
    —quiet
  </code></pre>
  
  <p>if I then do <code>git checkout -quit</code> or <code>git checkout "-quit"</code> or <code>git checkout \-quit</code> or <code>git checkout -- --quit</code> or anyother variant that come to mind I get:    </p>
  
  <pre><code> error: pathspec '-quiet' did not match any file(s) known to git. 
  </code></pre>
  
  <p>I looked into my <code>~/.gitconfig</code> file and did not find anything that could be related to this,</p>
