Subject: 26.1;
 byte compiler lost warning about calling define-key with wrong number
 of arguments
Date: Thu, 16 May 2019 16:24:21 -0500

Save a file with this line somewhere and call it foo.el:

(define-key "l" #'ignore)

Then call:

emacs -Q --eval "(setq byte-compile-error-on-warn t)" -batch -f batch-byte-compile foo.el

it _should_ emit an error since define-key gets called with the wrong
number of arguments. In Emacs 25.3, it does. In Emacs 26.1 and Emacs
built recently from git master, it does not.
