    eshell-eval-using-options: Avoid compiler warning differently
    
    * lisp/eshell/em-unix.el (eshell/time):
    * lisp/eshell/em-tramp.el (eshell/sudo):
    * lisp/eshell/esh-var.el (eshell/env): Remove artificial use of `args'.
    
    * lisp/eshell/esh-opt.el (eshell-eval-using-options): Silence warning
    when `args' is not used by `body-forms'.
