Then you could be absolutely sure. Because I read the other sources (not source of definition) I get confused, example in simple.el: (defvar minibuffer-history-isearch-message-overlay) (make-variable-buffer-local 'minibuffer-history-isearch-message-overlay) Then I ask myself why did not author straight write like: (defvar-local minibuffer-history-isearch-message-overlay) I ask myself why that, what is the difference... then I need assistance in clarification.
