bug#26221: (define function nil should work in 2.2

[Joshua Branson]

I can confirm this bug.  Eshell accepts (defun hello nil (print “Hello"))  And 
(hello)  works properly.

,languages elisp

(defun hello nil (print “Hello”))  doesn’t work.

P.S.  I didn’t even know (define function nil …) was a thing in elisp land.
