Hello, Emacs.

In the master branch, with emacs -Q, do

    M-: (funcall) RET

..  The error message one sees is

    (void-function nil)

..  This is wrong.  There is no function, nil or otherwise, supplied to
funcall.  The error message ought to be "Too few arguments", or
something like that.

The cause of the bug lies in Ffuncall in .../src/eval.c.  There, the
code uses args[0] without first checking that nargs > 0.
