title: Empty function in BASH
body: <p>I'm using FPM tool to create .deb package. This tool create before/after remove package from supported files. </p>
  
  <p>Unfortunatly the bash script generated by FPM contains such function</p>
  
  <pre><code>dummy() {
  }
  </code></pre>
  
  <p>And this script exit with an error:</p>
  
  <blockquote>
    <p>Syntax error: "}" unexpected</p>
  </blockquote>
  
  <p>Does BASH doesn't allow empty functions? Which version of bash/linux have this limitation?</p>
