Validate fails for current master

Hi, I'd love to push some Haddock changes, but for me validate on current master fails with: 1 caused framework failures 1 unexpected passes 86 unexpected failures Errors are of the form: - Multi-way if-expressions need MultiWayIf turned on + Multi-way if-expressions need -XMultiWayIf turned on Is one of you guys looking into this? Cheers, Simon
