add-log-current-defun cannot handle C++ names well. For
example, the current function:
int some_class::some_method(int arg)
{
// ...
}
If one invoke add-change-log-entry-other-window when point
is in this function, one would get
* some_file.cpp (class::some_method):
rather than
* some_file.cpp (some_class::some_method):
This is because add-log-current-defun in add-log.el calculates
the function name wrong. Below is the code:
;; Now find the right beginning of the name.
;; Include certain keywords if they
;; precede the name.
(setq middle (point))
(forward-word -1)
;; Is this C++ method?
;; ...
(forward-word -1) wouldn't put point before `some_class',
but puts point before `c' in `some_class'.
How about changing it to like this?
(while (not (looking-back "\\(^\\|[ \t]\\)"))
(backward-word 1))

How about making the intent clear:
(skip-syntax-backward "w_") ; word and symbol characters

Viewed at size of code differential, mine is the best:-P
If you agree with me, I'll install my fix.
If not, I'll install your fix.

I found this not complete yet, since only going back one sexp
sometimes cannot reach the beginning of a name. Please take
``class_1::sub_class_2::method'' as an example. A complete

Hmmm, I think the choice of ``skip-syntax-backward'' or
``forward-sexp'' is not more important than adding a
``while'' form; both the two functions work, but without
a ``while'' form, there is a bug.

Yes, you're right. Somehow I forgot to actually check that in a C++
buffer (vs. Emacs Lisp).
But I think your while condition
(not (looking-back "\\(^\\| \\|\t\\)"))
could be improved by specifying a LIMIT arg to looking-back
(1- (point))
and/or by anchoring the regexp with \=.
