Yes , only 1 message is enough. Cool tourdotimes, I didn't know.
So accordingly to your advice:


(defun indentTabs()
 (interactive)
  (   save-excursion ; cf
http://www.cs.tut.fi/lintula/manual/elisp/emacs-lisp-intro-1.05/emacs-lisp-intro_13.html#SEC145
restores point to its original position
    (   message "coucou"   )
    (goto-char (point-min))
(dotimes (i 100)
  (c-indent-command)
  (move-beginning-of-line 0)
  (next-line 1)
  )(message "fin partielle") ))

But debbuger displays still an error on c-indent-command:
Debugger entered--Lisp error: (void-function c-indent-command)
  (c-indent-command)
  (while (< i --dotimes-limit--) (c-indent-command) (move-beginning-of-
line 0) (next-line 1) (message "fin partielle") (setq i (1+ i)))
  (let ((--dotimes-limit-- 100) (i 0)) (while (< i --dotimes-limit--)
(c-indent-command) (move-beginning-of-line 0) (next-line 1) (message
"fin partielle") (setq i ...)))
  (dotimes (i 100) (c-indent-command) (move-beginning-of-line 0) (next-
line 1) (message "fin partielle"))
  eval((dotimes (i 100) (c-indent-command) (move-beginning-of-line 0)
(next-line 1) (message "fin partielle")))
  eval-last-sexp-1(nil)
  eval-last-sexp(nil)
  call-interactively(eval-last-sexp)
:
What is false with this command?
