title: Perforce: How do I sync the files in a specific subdirectory to a label
body: <p>If I issue</p>
  
  <pre><code>p4 sync ... 
  </code></pre>
  
  <p>it only syncs the files in my CWD and below to HEAD.</p>
  
  <p>However, I am trying to sync a single directory to a label name</p>
  
  <pre><code>p4 sync @LABEL_NAME ...
  </code></pre>
  
  <p>and the result seems to be that the entire workspace (all files tagged with that label) is then sync'ed to that label, as though I had not added the "...".</p>
  
  <p>Is this expected? And if so, how do I achieve what I want?</p>
