post-command-hook

[martin rudalics]

After updating my trunk I'm completely lost with the following issue:
With emacs -Q, switch to the buffer *Messages*, make it empty and
evaluate the following forms in it:

(defun foo ()
  (message "foo"))

(defun bar ()
  (message "bar"))

(add-hook 'post-command-hook 'foo)
(add-hook 'post-command-hook 'bar nil t)

Now move around that buffer.  Here it only runs the local hook function
"bar".  It does _not_ run the global hook function "foo".

All my earlier Emacs versions run both hooks alternately.

GNU Emacs 24.0.50.1 (i386-mingw-nt5.1.2600)

Help appreciated, martin
