How to make backward-kill-word and kill-word stop after it kills a newline character?

Question

kill-word and backward-kill-word deletes too much text:

foo(bar)
    <point>

Now if I press C-<backspace>:

foo(<point>

What I want is:

foo(bar)<point>

after pressing C-<backspace>, just like how the other editors do.

EDIT: Based on the answer from @gigiair, I'm trying to implement the command sequency in elisp, but I'm getting "Wrong number of arguments" when executing the code:

(defun leo/backward-kill-word ()
  "Better backward-kill-word."
  (interactive)
  (set-mark-command)
  (backward-sexp)
  (forward-sexp)
  (backward-delete-char-untabify))

I'm new to elisp, know nothing about.

This sequence does it :

 C-SPC                      ;; set-mark-command
 C-M-b                      ;; backward-sexp
 C-M-f                      ;; forward-sexp
 <backspace>                ;; backward-delete-char-untabify

This function executes this code :

(defun leo/backward-kill-word ()
  "Better backward-kill-word."
  (interactive)
  (let((beg (point)))
      (backward-sexp)
      (forward-sexp)
      (delete-region beg (point))))

This function is probably better

(defun leo/backward-kill-word ()
      "Better backward-kill-word."
      (interactive)
      (fixup-whitespace)
      (backward-delete-char-untabify 1))
