title: Hiding swp, ~ files in the default Vim file browser
body: <p>I'm using the default file browser in Vim a <em>lot</em>. But the annoyance is that it's showing swap files, <code>.orig</code>, <code>.php~</code> etc. Can I hide these files somehow?</p>
  
  <p>On a related note, why doesn't Vim always return to the file browser when pushing <kbd>Ctrl</kbd>-<kbd>6</kbd>?</p>
