Comment (by brillgen):
@lukeplant, the basic problem you've correctly raised is that list_display
allows for callables and hence arbitrary names can be used which are
simiar to the syntax for foreign key fields.
However, this problem exists for list_filter also: someone may define a
field with the name class__field and try to use that in list_filter as a
foreign key field. (i've just checked that you can indeed name a field
like that)
So we can't really be compensating for dev stupidity at the cost of
functionality as we haven't done in list_filter also.
Since all FKs always start with an alphabet are in the regex format
(.+__.+.*), the __unicode etc cases can be easily and correctly filtered
as is required to be done in list_filter.
