title: Trouble getting .gitignore files to work on OSX and Tower git GUI
body: <p>I have a cache directory I'm trying to have ignored by git which lives in my CMS's root directory here:</p>
  
  <pre><code>/files/cache/
  </code></pre>
  
  <p>I've tried the following variations in a .gitignore file at the root of the project:</p>
  
  <pre><code>/files/cache
  /files/cache/*
  files/cache
  files/cache/*
  </code></pre>
  
  <p>But the files still show up in Tower ready to be staged - the only other thing I can think of is that I'm using comments in the file like this:</p>
  
  <pre><code># comment
  /files/cache
  </code></pre>
  
  <p>Just not sure what I've missed sorry - any help would be much appreciated</p>
