[racket] Tiny question: Indent `for/fold'

A tiny, not very important question:

1. for/fold documentation:

(for/fold ([sum 0]
           [rev-roots null])
          ([i '(1 2 3 4)])
  (values (+ sum i) (cons (sqrt i) rev-roots)))

2. emacs default indent:

(for/fold ([sum 0]
           [rev-roots null])
    ([i '(1 2 3 4)])
  (values (+ sum i) (cons (sqrt i) rev-roots)))

3. DrRacket default indent:

(for/fold ([sum 0]
           [rev-roots null])
  ([i '(1 2 3 4)])
  (values (+ sum i) (cons (sqrt i) rev-roots)))

I prefer 1. I don't hate 2 but sometimes wonder if I should hand
indent it to 1, or, if is there some magic N for "(put 'for/fold
'scheme-indent-function N)" in emacs that I haven't discovered yet.

I'm curious what other people do? (I suppose "not care" is one valid choice?)
