title: Add file to subversion, while automatically adding parent directory node(s) if not added already
body: <p>When I want to add a file in a directory using</p>
  
  <pre><code>svn add directory/file.extension
  </code></pre>
  
  <p>and directory has not been added yet, I get an error that says that directory's node cannot be found and needs to be added first. So I can do</p>
  
  <pre><code>svn add directory --depth=empty
  svn add directory/file.extension
  </code></pre>
  
  <p>Can I automate the last two steps? Perhaps with a fitting parameter to svn add?</p>
