Comment (by bollmann):

 Upon a first investigation, it seems that the pretty printer in
 `Language.Haskell.TH.Ppr` functions correctly (at least concerning the
 parentheses around the lambda abstraction).

 It hence seems as if the pretty printer that is actually called when
 dumping the splice via -dth-dec-file is not
 `Language.Haskell.TH.Ppr.pprint`? I will investigate this further...
