code: def emptylineless(parser, token):
      
      nodelist = parser.parse(('endemptylineless',))
      parser.delete_first_token()
      return EmptylinelessNode(nodelist)
docs: Removes empty line.
  
      Example usage::
  
          {% emptylineless %}
              test1
  
              test2
  
              test3
          {% endemptylineless %}
  
      This example would return this HTML::
  
              test1
              test2
              test3
