Indent fails in emacs-lisp-mode with two-line docstring and (..) in second line of doc

[Mario Lang]

This bug report will be sent to the Free Software Foundation,
 not to your local site managers!!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

In GNU Emacs 20.7.2 (i386-debian-linux-gnu, X toolkit)
 of Sat Aug 18 2001 on gluck modified by Debian
configured using `configure  i386-debian-linux-gnu --prefix=/usr 
--sharedstatedir=/var/lib --libexecdir=/usr/lib --localstatedir=/var/lib 
--infodir=/usr/share/info --mandir=/usr/share/man --with-pop=yes --with-x=yes 
--with-x-toolkit=yes'

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

As the subject says, indentation (using TAB) does not work
with a function like this in emacs-lisp-mode:

(defun test()
  "doc
(example)"
  (and indent fails
       really))

I tested this behaviour with Emacs 20 and Emacs 21, and both appear to have
the same bug.
