Log message:
	py_decref: Don't check for NULL before calling Py_DECREF.
	
	The only difference between Py_DECREF and Py_XDECREF is that the latter allows passing
	in a NULL object, while the former prohibits it.  Given that, it's natural to expect
	the same from py_decref vs py_xdecref.

	* python/py-prettyprint.c (apply_val_pretty_printer): Check
	whether PRINTER is NULL before installing a Py_DECREF cleanup.
	* python/py-utils.c (py_decref): Don't check for NULL before
	calling Py_DECREF.
