That is what I mean, yes. Curious. Did you follow the recipe from
"emacs -Q"? Not all *vc-diff* buffers are affected.

Make that (111793,111794]. Revision 111794 introduces a new feature in
"easy-mmode.el" that allows major mode functions to disable global
minor modes by explicitly turning off the corresponding minor mode.
Unfortunately font-lock gets turned off in a change-major-mode-hook
function (font-lock-change-mode in "font-core.el"), which doesn't seem
to have been anticipated.

I can't say I understand why this doesn't cause global-font-lock-mode
to be disabled in all major modes in all circumstances. It could be a
question of whether font-lock-change-mode or
global-font-lock-mode-enable-in-buffers is earlier in
change-major-mode-hook.
