#9693: Custom Model.save() don't change relational data when editing via admin
(probably any other forms too)

Consider following models:
{{{
#!python
class A(models.Model):
name = models.CharField(max_length = 100)
class B(models.Model):
name = models.CharField(max_length = 100)
related = models.ForeignKey(to = A, null = True, blank = True)
def save(self):
if not self.name.startswith('@'):
self.name = '@' + self.name # this will work always
if self.related and self.related.name.startswith('@'):
self.related = None # won't work when editing via admin form
super(B, self).save()
}}}
This illustrates that submitting the data via admin interface will always
override relational changes in the custom Model.save() method. Other
fields, however, are changed as expected.
Calling save() under some other circumstances will always change
relational data as expected.
Any glue how to fix it? Thanks.
