Emacs does now.  So instead of the `pp' output of

(lambda nil
  (interactive)
  (let
      ((beg nil))
    (setq beg
          (point))
    (while
        (and
         (looking-at "[ \n ]")
         (not
          (eobp)))
      (forward-char))
    (delete-region beg
                   (point))))

you can have

(lambda ()
  (interactive)
  (let ((beg nil))
    (setq beg (point))
    (while (and (looking-at "[  \n ]") (not (eobp)))
      (forward-char))
    (delete-region beg (point))))

with `pp-emacs-lisp-code'.  And I'm sure there's a ton of stuff that can
be tweaked -- this is the sort of stuff that'd open ended, because
there's always something that can look just a bit prettier.

Have at it if you want to, but remember to add test cases.
