The manual doesn't mention either font-lock-fontify-buffer or
font-lock-fontify-region. Is that because the manual is incomplete or
because we are using font-lock in an undocumented way?

Nonetheless, if font-lock-default-fontify-buffer calls
font-lock-set-defaults, it seems that font-lock-default-fontify-region
should as well, thereby fixing the problem.
