title: tf diff /recursive /format:unified - how to not include folder names in output
body: <p>I want to generate the diff between two versions in TFS as a unified diff file. I do</p>
  
  <pre><code>tf diff $/TFSPATH/PROJECT/FOLDER /recursive /version:C12345~C12346 /format:unified
  </code></pre>
  
  <p>The generated output contains all the differences in files as I want to, but it also includes 4 additional lines for each folder it compares, even if there are no differences. So for a large project with few actual code changes between the given changesets, a diff file is generated consisting to 90+% of lines like: </p>
  
  <pre><code>Diff folder   : $/TFSPATH/PROJECT/FOLDER/SUB/SUB1;C12345
  against folder: $/TFSPATH/PROJECT/FOLDER/SUB/SUB1;C12346 
  ===================================================================
  
  Diff folder   : $/TFSPATH/PROJECT/FOLDER/SUB/SUB1/SUB;C12345
  against folder: $/TFSPATH/PROJECT/FOLDER/SUB/SUB1/SUB;C12346 
  ===================================================================
  </code></pre>
  
  <p>Is there any way to tell <code>tf</code> to not include those lines? </p>
  
  <p>Thanks</p>
