Font-lock was turned off by default in versions 21.1 to 21.4 since its performance impact was not well-behaved enough. Quite a bit of fixes went into font-lock in order to make it a defensible choice to enable it by default. People were _expecting_ downsides from font-locking, and we told them so, and they had to enable it manually. The situation is different for Emacs 22. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
