#2995: ghc -Wall does not complain about unnecessary data constructor imports

-----------------------------+----------------------------------------------
If it is enough to import:
import SomeModule(SomeType)
Then ghc should complain (warn) when importing:
import SomeModule(SomeType(..))
or:
import SomeModule(SomeType(SomeConstructor))
But it doesn't output any complaint or warning.
