title: "p4 diff -du" on linux adds /tmp.paths
body: <p>When I run 'p4 diff -du' on linux it includes tmp file and extra file system file into the  the headers:</p>
  <pre><code>--- //sandbox/...
  +++ /home/...
  --- /tmp/tmp.12345.123
  +++ /home/....
  </code></pre>
  <p>It is not happening on mac and it is really annoying. Is there a way around it beyond using grep to filter out unwanted lines?</p>
