commit 507c9683dafd9c237ea735a846352b0ea55dc3fb
Author: Herbert Valerio Riedel <hvr at gnu.org>
Date:   Sun Mar 22 08:22:03 2015 +0100

    Update haskeline submodule to 0.7.2.1 release tag
    
    This fixes compilation under windows with pre-AMP GHCs
    although it's not clear if bootstrapping GHC was affected.
    (see https://github.com/judah/haskeline/issues/20 for details)
    
    (cherry picked from commit 899cb3e768bf495b396f59dc2b49b7b10eb4ad8c)
