Note that this only affects display of the "Index of /blah/" line.  I could
write a test for this, but I only see browser tests for this file.  Easy enough
to write one of those that tests this, but seems like overkill.

   std::string unescaped_path = net::UnescapeURLComponent(response_url.path(),
                                                          unescape_rules);
   SendDataToClient(net::GetDirectoryListingHeader(
       ConvertPathToUTF16(unescaped_path)));
 
   // If this isn't top level directory (i.e. the path isn't "/",)
   // add a link to the parent directory.
   if (response_url.path().length() > 1) {
     SendDataToClient(net::GetDirectoryListingEntry(
         base::ASCIIToUTF16(".."), std::string(), false, 0, base::Time()));
   }
 }
 
 void FtpDirectoryListingResponseDelegate::SendDataToClient(
     const std::string& data) {
   if (client_)
     client_->didReceiveData(loader_, data.data(), data.length(), -1);
