I pushed a documentation fix to emacs-26:

  commit 98e5fb9bf3b49bea82a4d3e38be20415bd7f7684
  Author: Charles A. Roelli <charles <at> 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.

The following four commands all claim to "kill the pending input",
which they don't actually seem to do.  Should the documentation or
implementation be changed?


(defun comint-interrupt-subjob ()
  "Interrupt the current subjob.
This command also kills the pending input
between the process mark and point."
  (interactive)
  (comint-skip-input)
  (interrupt-process nil comint-ptyp)
  ;; (process-send-string nil "\n")
  )

(defun comint-kill-subjob ()
  "Send kill signal to the current subjob.
This command also kills the pending input
between the process mark and point."
  (interactive)
  (comint-skip-input)
  (kill-process nil comint-ptyp))

(defun comint-quit-subjob ()
  "Send quit signal to the current subjob.
This command also kills the pending input
between the process mark and point."
  (interactive)
  (comint-skip-input)
  (quit-process nil comint-ptyp))

(defun comint-stop-subjob ()
  "Stop the current subjob.
This command also kills the pending input
between the process mark and point.

WARNING: if there is no current subjob, you can end up suspending
the top-level process running in the buffer.  If you accidentally do
this, use \\[comint-continue-subjob] to resume the process.  (This
is not a problem with most shells, since they ignore this signal.)"
  (interactive)
  (comint-skip-input)
  (stop-process nil comint-ptyp))
