Comment:

 This ticket seems fixed. There are almost 2 years since this ticket was
 created, and Django has continually evolved. For example, the code
 fragment shown in the ticket's description has actually some little
 changes.

 {{{
                # if isinstance(f.rel, models.ManyToOneRel):  <= old
 line...
                if isinstance(f.remote_field, models.ManyToOneRel):
                     field_val = getattr(result, f.name)
                     if field_val is None:
                         result_repr = empty_value_display
                     else:
                         result_repr = field_val
                 else:
                     result_repr = display_for_field(value, f,
 empty_value_display)
                 if isinstance(f, (models.DateField, models.TimeField,
 models.ForeignKey)):
                     row_classes.append('nowrap')
 }}}

 I analysed the tests where this fragment of code is involved and I've the
 following result:
 * Admin tests where the condition  `if isinstance(f.remote_field,
 models.ManyToOneRel)` is used:
 ||= Test Name =||= Number of Tests =||
 || admin_changelist || 10 ||
 || admin_views || 48 ||
 || admin_widgets || 1 ||
 * Admin tests where the condition  `if isinstance(f.remote_field,
 models.ManyToOneRel)` returns true:
 ||= Test Name =||= Number of Tests =||
 || admin_changelist || 7 ||
 || admin_views || 13 ||
 || admin_widgets || 1 ||
 * Admin tests where the condition  `if isinstance(f.remote_field,
 models.ManyToOneRel)` returns false:
 ||= Test Name =||= Number of Tests =||
 || admin_changelist || 10 ||
 || admin_views || 48 ||
 || admin_widgets || 1 ||

 This condition `if isinstance(f.remote_field, models.ManyToOneRel)` in
 admin_list template tag works good. I think that there are not other
 ticket related specifically with that, and the Django admin
 `items_for_result` method works fine. Is still necessary create other test
 specifically for that condition??
 I think that this ticket could be closed as fixed.
