I read this differently - when you have (let ((var 'val)) (make-variable-buffer-local 'var)) it will not set buffer-local value to 'val. You have to set the buffer value explicitly via set/setq outside let context. And the patch makes `case-fold-search' buffer-local internally. Nothing needs to call (make-variable-buffer-local 'case-fold-search). --=20 Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at .
