title: How to see 'git svn dcommit' changes before dcommitting?
body: <p>With <code>svn-git</code>, how can I see what is about to be committed
  with <code>git svn dcommit</code>?</p>
  
  <p>Here are the commands I run:</p>
  
  <pre><code>git svn  clone file:///svn/test1 test1-git
  cd test1-git
  echo "first line" &gt; test1.txt 
  git add test1.txt 
  git commit 
  </code></pre>
  
  <p>Now it's committed to the git repository -- good. But before I run <code>git svn dcommit</code> I'd like to see a diff that contains the changes that would be committed to the SVN repository.</p>
