add-log-current-defun doesn't work with Go code

[zvbuhl]

add-log-current-defun doesn't know how Go code is formatted. Fortunately, there's a variable add-log-current-defun-function, which can be used to integrate with Go mode:

(defun go-current-def-name ()
  "Return the name of the function at point, or nil."
  (save-excursion
    (go-goto-function-name)
    ;; get the next word
    (buffer-substring-no-properties (point)
				    (progn (forward-sexp 1)
					   (point)))))
(add-hook 'go-mode-hook (lambda ()
                          (setq add-log-current-defun-function #'go-current-def-name)))

It'd be great to have this (or something slightly smarter) added to Go mode.
