title: How to format regexes in find-name-dired?
body: <p>When calling <code>M-x find-name-dired</code> you will be prompted for a root directory and a filename pattern.</p>
  
  <p>What's the proper find regex for multiple file extensions? Eg using <code>*(txt|html)</code> gets converted to <code>find . \( -iname \*\(coffee\|html\) \) -ls</code>, which doesn't work. Is there any way to convert to the <code>-o</code> or <code>-regex</code> mentioned here: </p>
