commit 4c7da9c557ac5990fb4ccdd6145e0d2487a57219
Author: Ben Gamari <ben at smart-cactus.org>

    Update haddock submodule
    
    Also rename and move the horribly named isVanillaLSig to Haddock as
    isUserLSig, reflecting the fact that it returns whether the signature
    was provided by the user or generated.
