I have just fixed this problem (I hope!) in both the Emacs-22 branch and the trunk. Basically, the contorted functionality in add-log.el has been superseded by optimised routines in cc-cmds.el. On my 1.2 GHz Athlon machine, C-x 4 a now takes around 4 seconds at the end of lisp.h, in the trunk. It's somewhat faster in the Emacs-22 branch, but I don't know why. I think this is fast enough. -- Alan Mackenzie (Nuremberg, Germany).
