body: <p>I open several files in Vim by, for example, running</p>
  
  <pre><code>vim a/*.php
  </code></pre>
  
  <p>which opens 23 files.</p>
  
  <p>I then make my edit and run the following twice</p>
  
  <pre><code>:q
  </code></pre>
  
  <p>which closes all my buffers.</p>
  
  <p><strong>How can you close only one buffer in Vim?</strong></p>
