documentation: true outputs to stdout when -v0 is enabled

[mpickering]

-v0 should never output anything to stdout. cabal-install should be silent in this mode of operation.

If you enable documentation: true in a cabal file then a lot of junk from haddock is output.

Perhaps passing --no-warnings to haddock is sufficient.

[harpocrates]

I don't think --no-warnings will be enough. Even besides that, the Haddock codebase still has a bunch of unguarded putStrLn's for emitting various messages.

Once all that fixed, I think it should be enough to make sure that -v0 in Cabal implies -v0 in Haddock.

@harpocrates Is there a corresponding upstream ticket?

[harpocrates]

Nope, but there probably should be. There’s some nice beginner-friendly refactor work there to do.
