title: Why GitHub doesn't display the file history when the commit history does?
body: <p>I've recently found a strange behaviour about GitHub repository.</p>
  
  <p>When I choose file and then its history (because I want to see all changes/commits to this file) there is only one - last commit: <a href="https://github.com/MarianMacik/Kartoteka/commits/master/src/main/java/cz/muni/fi/macik/kartoteka/beans/AuthenticationBean.java" rel="nofollow"><code>beans/AuthenticationBean.java</code></a>. </p>
  
  <p>But when I check all the commits to the whole repository (main page with folder structure where language statistics are present, number of commits and so on) I can find 5 commits which contain changes to this file, as <a href="https://github.com/MarianMacik/Kartoteka/commit/2787506425ee23adf6dfc7f0b7b2d9d446a61c8a" rel="nofollow">this commit</a>. </p>
  
  <p>I don't know if it has something to do with one revert I made throughout the project.<br>
  I've read somewhere that revert may cause something like history reset.<br>
  But I would be pleased if you can help or explain this situation to me.</p>
