title: Redirect URL with question mark and wildcard
body: <p>In .htaccess, how can I redirect all URLs like this </p>
  
  <pre><code>site.com/?author=X
  </code></pre>
  
  <p>(where X is any number) </p>
  
  <p>to </p>
  
  <pre><code>site.com/theonlyauthor
  </code></pre>
  
  <p>(I've seen many posts about redirecting with either a question mark or with a wildcard, but not both.)</p>
