title: SVN log not showing all the revisions made to a file
body: <p>I've started using SVN before a few weeks. I am facing a weird problem right now. We have a file, which was added by me to the repository. Another developer checked it out yesterday, made some modifications to it, and comitted it to the repository. Today, I made some modifications to that file and comitted it to the repository. But it didn't ask me to merge the changes when I comitted that file, so now I only have the version which I had modified, and the changes done by the other developer are not even showing up in the log.</p>
  
  <p>What am I missing here? How should I go about merging both the changes? We are using TortoiseSVN as a client.</p>
  
  <p>EDIT: All other developers are able to see the log entry in their SVN clients!! So, it seems that the commit was properly done.</p>
