  Hum, the documentation string comes from the C function description.
I thing the binding code actually transform the result to a Python
string object and free the xmlChar * using xmlFree().
  In practice, the generated wrapper function
    libxml_xmlEncodeEntitiesReentrant() in libxml2-py.c 
calls libxml_xmlCharPtrWrap() wiith the result and that routine
does that :

      ret = PyString_FromString((char *) str);
      xmlFree(str);
