audit trail dont log field with not callable default attribute

[whitespy]

I have a model:

class Foo(models.Model):
status = models.CharField(_('status'), max_length=30, choices=STATUS_CHOICES,
default=STATUS_CREATED)
...

audit_trail_watch(Order, fields=['status'])

When I create an entity of the model, audit trail does not log status field change, because there are default = STATUS_CREATED. This should be considered a mistake or feature?

Yep, it's a feature, but now I'm thinking it's not a good idea.
