Okay, I changed it to make it hopefully clearer.

Great catch.  No one has complained about this, so clearly it's OK for
font-lock-keywords-case-fold-search to be nil.  I removed the bogus
8-year-old setting of font-lock-keywords-case-fold-search.

font-lock-keywords-case-fold-search docstring should make it more clear
that font-lock-defaults erases it.

There is one victim in the tree.  `lisp-mode' does:

  (make-local-variable 'font-lock-keywords-case-fold-search)
  (setq font-lock-keywords-case-fold-search t)

but the value of font-lock-keywords-case-fold-search in a lisp-mode
buffer is nil, that's because font-lock-defaults does a
kill-local-variable on it...
