Add log bug

["Herbert Euler" <herberteuler@hotmail.com>]

There is a bug in add-log.el, in the function
`add-log-current-defun'.  There was a fix; but it is not complete.
The old description of the bug can be found at

    http://lists.gnu.org/archive/html/emacs-devel/2006-09/msg00857.html

The problem exists yet now.  If you put point in the body of the C++
function below:

void
web_slim::slim_dirent::clear ()
{
  for (slim_dirent_seq::iterator i = sub.begin (); i != sub.end (); ++i)
    i->clear ();
  sub.clear ();
}

`add-change-log-entry-other-window' would try to add a log entry for
function `slim_dirent::clear', rather than the desired
`web_slim::slim_dirent::clear'.

The old fix changed `forward-word' into `forward-sexp', but the latter
one only moves one sexp.  So the point is put before `slim_dirent' in
the above example.  A complete fix could be:

*** add-log.el.~1.146.2.22.~    Mon Nov 13 10:58:16 2006

                              (setq middle (point))
!                              (forward-sexp -1)
                              ;; Is this C++ method?
                              (when (and (< 2 middle)
                                         (string= (buffer-substring (- 
middle 2)

                              (setq middle (point))
!                              (while (not (looking-back "\\(^\\| 
\\|\t\\)"))
!                                (forward-sexp -1))
                              ;; Is this C++ method?
                              (when (and (< 2 middle)
                                         (string= (buffer-substring (- 
middle 2)

This is not a big problem; but it is still a bug.  Since it will take
long between two releases, I think it could be good of fixing it
before this release.
