 Show that `Type u₁` is cartesian closed, and `C ⥤ Type u₁` is cartesian closed for `C` a small
 category in `Type u₁`.
 Note this implies that the category of presheaves on a small category `C` is cartesian closed.

It makes the following changes:

converts "--porting note" into "-- Porting note";
converts "porting note" into "Porting note".
