title: Deno read access to CWD
body: <p>How can I allow read access to CWD (current working directory) used by <code>Deno.cwd()</code>?<br />
  <strong>I want explicit permission only for CWD.</strong> I don't want to allow every read with plain <code>--allow-read</code> flag.</p>
  <p>I've tried to pass <code>CWD</code> as a parameter but it doesn't work.</p>
  <pre><code>deno run --allow-read=CWD index.ts
  </code></pre>
  <pre><code>Uncaught PermissionDenied: read access to &lt;CWD&gt;, run again with the --allow-read flag
  </code></pre>
  <p>Index.ts is just:</p>
  <pre><code>console.log(Deno.cwd());
  </code></pre>
  <p>I am using <em>deno 1.2.0</em>.</p>
