In some cases it looks prettier, but in others it looks uglier.  For
example

#+begin_src emacs-lisp
(let ((x 1) (y 2))
  (+ x y))

(defun f (n) (1+ n))
#+end_src

becomes

#+begin_src emacs-lisp
(let
    ((x 1)
     (y 2))
  (+ x y))
(defun f
    (n)
  (1+ n))
#+end_src

after your treatment.  Too many added line breaks for my gusto, but OTOH
the empty line between the two expressions has disappeared.

pp may be ok for improving how an evaluation result is presented to the
user, but it's IMHO by far not suitable for reformatting hand-written
code.
