commit 1687f999dfa09e975e679f1fdec807fc87de40e8
Author: Herbert Valerio Riedel <hvr at gnu.org>

    Update transformers submodule to latest v0.5.0.0
    
    `transformers-0.5.0.0` will be the next version of `transformers`
    and this is the designated version to be used for GHC 8.0.1
    
    This needs to update the haskeline submodule in order to relax
    the upper bound for the major version bump to 0.5
