title: Vim's :open does not tab complete, what does?
body: <p>Instead of tab completed file or directory names, I see <code>^I</code></p>
  
  <pre><code>:open ./lib/^I^I^I
  </code></pre>
  
  <p>Is there another command that would offer tab completion, or perhaps another solution?</p>
  
  <p>I'm considering replacing the following mapping with something that would use buffers, but want to keep tab completion.</p>
  
  <pre><code>map &lt;C-O&gt; :tabnew ./
  </code></pre>
