Actually, that is incorrect...-ish.  The specific problem happens when
you encounter a comma or comma-at while not inside a backquote.  With
72334 this is not a problem, but without it you end up with the
(unevaluated) form
  (foo bar . ,baz)
printed as
  (foo bar . (\, baz))
which is obviously not ideal.

It /should/ be possible to lightly change the patch to have it work, by
checking `new_backquote_output' in case the car is a comma or a comma-at
but honestly I would just rather 72334 be pushed instead.
