Commitf0f73b3

committed

Allow CASE statement to contain *only* untyped result clauses or nulls.

Almost worked before, but forgot one place to check. Reported by Tatsuo Ishii.Still does not do the right thing if inserting into a non-string target column. Should look for a type coersion later, but doesn't.
