title: git status shows a file that I have listed explicitly in my .gitignore file
body: <p>I have the following line in my .gitignore file:</p>
  
  <pre><code>var/www/docs/.backroom/billing_info/inv.pl
  </code></pre>
  
  <p>but when I type 'git status' I am told the following:</p>
  
  <pre><code>#   modified:   var/www/docs/.backroom/billing_info/inv.pl
  </code></pre>
  
  <p>I dont understand how a file which is explicitly listed as an ignore pattern could be listed as modified when I want git to ignore it.</p>
  
  <p>There are no lines starting with a ! in my .gitignore file</p>
  
  <p>Here is my entire .gitignore file for reference: <a href="http://pastebin.com/Jw445Qd7" rel="noreferrer">http://pastebin.com/Jw445Qd7</a></p>
