      Description

      When a function is invoked with a wildcard * for its parameter, it should be passed all of the columns in the expansion, exception in the special case of COUNT, where none of the columns should be passed.

      As part of this issue, we also need to test qualified wildcards (e.g. t.*) and Hive's extension for regular-expression selection of column subsets.
