From b7a74c6702f087fde99f44f12d99c66afcf5790d Mon Sep 17 00:00:00 2001

Subject: Show where instances are defined (#748)

* Indicate source module of instances

Above instance, we now also display a link to the module where the
instance was defined. This is sometimes helpful in figuring out
what to import.

* Source module for type/data families too

* Remove parens

* Accept tests
