Log Message:
-----------
When displaying a Var that is a reference to a column of an unnamed join,
try to display it as a reference to the underlying column instead. This
is a legitimate substitution (it wouldn't be for a named join) and it
fixes some cases where the display would otherwise be ambiguous. Per
example from Sim Zacks.
