Comment (by codefisher):
You say "Probably a good idea to recommend fetching the object from the
database after saving in order to get the new value if you are still using
the object after save()."
That is already done, at least on the latest dev docs:
https://docs.djangoproject.com/en/dev/ref/models/queries/#f-expressions
But the effect of calling save more then once is no where to be seen, and
really not that expected.
