Ok, take your time. I just wanted to make sure I sent this to the right place.

I changed "[[:space:]\n]" -> "[[:space:]]\n" because I think that's what you meant.


I posted the result of these change at the bottom of this reply.

I'm new to contributing patches. Is there anything else I need to do to get this
into emacs?

```elisp
(if (or
     (= (point) calculate-lisp-indent-last-sexp)

     (eq (char-after (1+ containing-sexp)) ?:)

     (eq (char-before containing-sexp) ?')

     (let ((quoted-p nil)
           (point nil)
           (positions (nreverse (butlast (elt state 9)))))
      (save-excursion
        (while (and positions (not quoted-p))
         (setq point (pop positions))
         (setq quoted-p
          (or (eq (char-before point) ?')
           (goto-char (1+ point))
           (looking-at-p "[[:space:]]\n*quote\\_>")))))
      quoted-p))
    ;; Containing sexp has nothing before this line
    ;; except the first element.  Indent under that element.
    nil
  ;; Skip the first element, find start of second (the first
  ;; argument of the function call) and indent under.
  (progn (forward-sexp 1)
   (parse-partial-sexp (point)
    calculate-lisp-indent-last-sexp
    0 t)))

```

I did you see your messages, just haven't had so much time for handling
Emacs bugs recently.  I was going to forward it to the list before
replying, so thanks for doing that.

I mixed things up a bit, I meant to say

    (looking-at-p "[[:space:]\n]*quote\\_>")

The "\n" is needed because it typically has comment-ender syntax instead
of space syntax.  "\\>" matches end of word, "\\_>" is end of symbol.

I think relying on the mode's syntax table makes sense, though it
probably doesn't matter a whole lot either way.
