title: Can git ignore a specific line?
body: <p>I'm using git to sync to phonegap while testing on the phone's native browser. As such I have the following line:</p>
  
  <pre><code>var isPhoneGap = false;
  </code></pre>
  
  <p>Obviously I change this when building, but is there any way I can set up git to ignore this one line or do I have to go and put it in its own file and ignore it that way?</p>
  
  <p>I'm using Gitx and the terminal on OSX 10.6.</p>
