1014	Allow _pre_save and _pre_delete to stop save / delete	django@…	Adrian Holovaty	It'd be useful in some situations if a _pre_save or _pre_delete hook could signal that the saving or deleting shouldn't go ahead. Throwing an exception isn't the best way to handle it if it's not actually exceptional behaviour. For instance, in a version control system, on _pre_delete you might wish to alter the status to 'deleted' but stop the actual object from being deleted.	enhancement	closed	Metasystem		normal	fixed			Unreviewed	0	0	0	0	0	0
