	(python_string_to_target_python_string): New Functions.
	* python/python-prettyprint.c (pretty_print_one_value): Likewise.
	(print_string_repr): Refactor to logic to account for PyObject
	returned strings.
	(apply_varobj_pretty_printer): Likewise.
	* python/python-value.c (valpy_string): Parse length keyword. Use
