Comment (by mpickering):

 Here is the preprocessed source. There is an extra line inserted after the
 pragma.

 {{{
 {-# LINE 1 "test.hs" #-}
 # 1 "test.hs"
 # 1 "<built-in>" 1
 # 16 "<built-in>"
 # 1
 "/Users/matt/Downloads/ghc-7.10.1.app/Contents/lib/ghc-7.10.1/include/ghcversion.h"

 # 17 "<built-in>" 2
 # 1 "test.hs" 2
 {-# LANGUAGE CPP
   #-}

 module Foo where

 foo :: String
 foo = True
 }}}
