docs: Return a copy of the string passed to the filter wrapped after
      ``79`` characters.  You can override this default using the first
      parameter.  If you set the second parameter to `false` Jinja will not
      split words apart if they are longer than `width`. By default, the newlines
      will be the default newlines for the environment, but this can be changed
      using the wrapstring keyword argument.
  
      .. versionadded:: 2.7
