title: check the last commit message in subversion
body: <p>Why is it when I execute the following command just after making a commit I get the commit message, but all other times I just get a line of dashes?</p>
  
  <pre><code>svn log -r head
  </code></pre>
  
  <p>Quite often I want to browse to a branch in my filesystem, check what branch it represents in subversion and check what the last commit message was, but this command only seems to work when I run it <em>just</em> after making a commit.</p>
