I use a similar thing quite often and instead of
fixup-whitespace. Its a useful feature IMO.

Here original behaviour is available via arg.

(defun my-fixup-whitespace (&optional arg)
  "Fixup white space between objects around point.
Leave one space or none, according to the context.
With ARG, don't kill \\r\\n\\f"
  (interactive "*P")
    (if (eq 4 (prefix-numeric-value arg))
      ;; 2007-11-28 address@hidden changed section start
      (unless (bolp)
        (skip-chars-backward " \t\r\n\f"))
      (let ((start (point)))
      (skip-chars-forward " \t\r\n\f")
      (delete-region start (point)))
    ;; 2007-11-28 address@hidden changed section end
    (if (or (looking-at "^\\|\\s)")
            (save-excursion (forward-char -1)
                            (looking-at "$\\|\\s(\\|\\s'")))
      (insert ? )))))
