You need Cabal 1.12 for '--enable-library-coverage'. The only place
it's documented is in 'cabal configure --help' (a major oversight on
my part). The online docs for Cabal are only from version 1.10 anyway,
so that wouldn't have helped.

I'm sorry for your struggles getting the detailed type to work. It's a
known issue: the detailed test interface is intentionally disabled in
all the released versions because it's going to change. That's why
none of the test libraries support it yet and why you weren't able to
get it to work.
