And JIT lock takes care of errors too:
(defmacro jit-with-buffer-unmodified (&rest body)
"Eval BODY, preserving the current buffer's modified state."
(declare (debug t))
(let ((modified (make-symbol "modified")))
`(let ((,modified (buffer-modified-p)))
(unwind-protect
(progn ,@body)
(unless ,modified
(restore-buffer-modified-p nil))))))
(defmacro with-buffer-prepared-for-jit-lock (&rest body)
"Execute BODY in current buffer, overriding several variables.
Preserves the `buffer-modified-p' state of the current buffer."
(declare (debug t))
`(mumamo-jit-with-buffer-unmodified
(let ((buffer-undo-list t)
(inhibit-read-only t)
(inhibit-point-motion-hooks t)
(inhibit-modification-hooks t)
deactivate-mark
buffer-file-name
buffer-file-truename)
,@body)))
