I managed to run intero on #nixos. It was all stack's fault!

Long story short, when run on nixos without nix being explicitly enabled in stack.yaml, stack prints "Note: Enabling Nix integration..." message, which fucks up parsing in intero.el.

Curious thing is, I can't find that exact message in stack source code anywhere.

@pureevil It was removed back in May: https://github.com/commercialhaskell/stack/commit/e74b0c05415329119f60fe840191f699ac1050b5#diff-dd24cfdc1aa1c30ec6a9b98528de6d55L47

A very short-lived feature, to be sure. It was added at the end of March: https://github.com/commercialhaskell/stack/commit/b60819cbe9dc5e97cdc3771a0fb538d21ab190d2#diff-dd24cfdc1aa1c30ec6a9b98528de6d55R47

(When `git grep` doesn't work, I fire up `git log --patch` and search through *that*.)

@minoru oh, thanks! That explains it. Looks like it made it's way into v1.7.1.

Another curious thing is that stack devs don't use MultiWayIf for some reason. Stack is weird.
