Query with duplicate output column names drop/overwrites duplicate colums

[andig]

Consider this join query:

select d1.*, d2.* from delta d1 inner join delta d2 where d1.new==d2.old

This will result in column names from d1, d2 to be duplicated. Unfortunately, running this query via sqlite-utils, only one set of output columns is returned, probably being overridden in the map.
