  * Pretty print ffi import strings as proper Haskell strings
  foriegn import ccall "foo\\bar.h baz" baz :: IO ()
  Since the import spec string is actually parsed by the compiler as a
  Haskell string we should use show to pretty-print it.
  For one thing this means that windows backslash directory separators
  get escaped properly "foo\\bar".
