title: Whitespaces in URL causing wget to fail
body: <p>I have a URL like so:<br>
  <code>http://localhost:8999/createAudio?method=createAudio&amp;sessionId=1234&amp;text=${line}&amp;voice=Paul&amp;encoder=MP3";</code><br>
  Where <code>${line}</code> is "This is such a nice day."<br>
  I am using <code>wget</code> to capture the output of the above http request like so:<br>
  <code>cURL="http://localhost:8999/createAudio?method=createAudio&amp;sessionId=1234&amp;text=${line}&amp;voice=Sangeeta&amp;encoder=MP3";<br>
  wget -O test.html ${cURL}</code>  </p>
  
  <p>My problem is that the http request cuts at the first instance of a white space. So the http request that would be issued would go like:<br>
  <code>http://localhost:8999/createAudio?method=createAudio&amp;sessionId=1234&amp;text=This</code>  </p>
  
  <p>How do I ensure that the entire <code>${line}</code> gets used in the http request?</p>
