Subject: * lisp/calculator.el (calculator-define-key): Undo last change
X-Git-Tag: emacs-26.0.90~2896
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=6148555ee5a3d0139ae517803718b3e0357933c7;p=emacs.git

* lisp/calculator.el (calculator-define-key): Undo last change

Make map argument mandatory instead (bug#22106).
(calculator-add-operators): Pass the argument that's not optional any more.
