Syntax highlighting and indentation fails when there are parenthesis in the doc string

Syntax highlighting and indentation fails when there are parenthesis in the doc string

[Lennart Borgman]

This is for emacs 21.3. To show the bug take the code below and put it in a
buffer in emacs-lisp-mode. Then follow the instructions in the doc string.

I have tested this on ms windows.

(defcustom some-variable t
  "Some doc with paretheses:
(this is the line that give the error)
This will mess indentation and syntax coloring in the properties part below.
Please delete and put back lines below to show the problem!
Do the same thing with the line above with parenthesis deleted."
  :tag "Some Tag"
  :group 'some-group
  :type 'boolean
  :set (lambda (symbol value)
  (add-to-list 'some-hook 'the-hook-fun)
  (set-default symbol value)
  (unless (boundp 'some-key) (setq some-key "\C-c\C-z"))
 )
  )

This is not a bug, it's documented somewhere (although I can't find
the reference right now). To prevent this either prepend open
parentheses in a docstring with a backslash - I think that's the
recommended way - or set open-paren-in-column-0-is-defun-start to NIL.

Cheers,
Edi.
