Comment (by goldfire):

 I guess the question is this: should `-fprint-explicit-kinds` print
 unboxed tuple types in prefix so that the levity arguments are displayed?
 I think: no. But perhaps `-fprint-explicit-runtime-reps` should, and GHC
 should be taught to tell the user about this flag instead of `-fprint-
 explicit-kinds` in this scenario.
