title: Ignore a specific file in ack 2.0 to avoid Permission Denied error
body: <p>I have a file that causes Ack 2.0 to report a "Permission denied" error, so I've been trying to get it to ignore the file.</p>
  
  <p>I have tried the following in my ackrc</p>
  
  <pre><code>--type-set=lockfile:match:/NameOfLockfile/
  --type=nolockfile
  </code></pre>
  
  <p>But it still reports the error "Permission denied".  Using the same syntax I have confirmed that I can get it to not search in the given file (yet it must still try to access it since it gets permission denied error)</p>
