- When downloading compressed content over HTTP and the app as asked libcurl

to automatically uncompress it with the CURLOPT_ENCODING option, libcurl

  documented amount. An application could thus get tricked into badness if the
  maximum limit was trusted to be enforced by libcurl itself (as it is
  documented).
