Have done the following macro, but calling `C-h f tak` shows the definition
as 

(tak &rest ARGS)

rather than

(tak &rest _ARGS)

(defmacro tak (&rest _args)
  "Performs no action, no matter how many arguments are passed."

  nil)

This is a feature: the leading '_' is an indication that the argument
is unused, but the argument's name is 'args', without the underscore.

This is not a bug.

Don't you need to show users that the argument is unused?

We could add that as a new feature, but usually the docstring says it
instead, so it would often be redundant.
