commit 9ea96d5ff04e018c33def628e394ec55c0416662

    Improve pretty-printing of HsWrappers
    
    Reduces un-neede parens.
    
    Also -fprint-typechecker-elaboration now makes type applications
    and casts in expressions also appear.  (Previously those were
    confusingly controlled by -fprint-explicit-coercions.)
    
    (cherry picked from commit d0846243747213218cba856d5c322016bd3e6d9e)
