title: How to create an empty file from an empty diff using the patch utility?
body: <p>I have an output from <code>diff -au</code> (if it matters, this command is used within <code>svn diff</code>), like:</p>
  
  <blockquote>
    <p>Index: src/test.txt
     ===================================================================</p>
  </blockquote>
  
  <p>It's a newly created empty file.
  How can I force patch utility to create this empty file?</p>
