Missing lambdas in Monad laws documentation
Summary
In the documentation specifying the Monad laws in GHC.Base, the lambdas used
in the law for m1 <*> m2 seem to be correctly escaped in the source:
but once the documentation is rendered they have disappeared:
m1 <*> m2 = m1 >>= (x1 -> m2 >>= (x2 -> return (x1 x2)))
