Hi Lionel,

Thanks. I got this far:

(defun julia-fill-string ()
  (let* ((p (point))
         (s (syntax-ppss)))
    (when (fourth s)                     ; inside a string
      (let ((start (ninth s))
            (end (MISSING PIECE)))
        (ess-blink-region start end)
        (fill-region start end nil nil nil)))))

but I don't know what's the simple way of finding the end of a string,
preferably using the syntax table (MISSING PIECE in the code above). I
could, of course, go to the beginning, determine if it is """ or ", then
find it later on, but I am wondering if there is a better way.
