I pushed a documentation fix to emacs-26:

  commit 98e5fb9bf3b49bea82a4d3e38be20415bd7f7684
  Author: Charles A. Roelli <charles@aurox.ch>
  Date:   Mon Jan 15 21:14:05 2018 +0100

    Remove incorrect documentation in comint.el

    * lisp/comint.el (comint-interrupt-subjob, comint-kill-subjob)
    (comint-quit-subjob, comint-stop-subjob): Remove incorrect
    documentation.  (Bug#30079)

If there's any interest in reinstating the old, documented (but
unimplemented) behavior in the master branch, please reopen.
