Shortdoc:

    >> (seq-empty-p arg &rest args)

C-h f

    >> (seq-empty-p SEQUENCE)


The shortdoc implies that this is legal:

(seq-empty-p '() '())

but it gives:

Debugger entered--Lisp error: (wrong-number-of-arguments (1 . 1) 2)
  #f(compiled-function (list) "Optimized implementation of `seq-empty-p' for lists." #<bytecode -0x155616500a964cb3>)(nil nil)
