Hi,

        After an `async-shell-command' finished, I tried to
        navigate its buffer with the arrow-keys and got the
        following:

Debugger entered--Lisp error: (wrong-type-argument processp nil)
  process-mark(nil)
  comint-after-pmark-p()
  (if (comint-after-pmark-p) (comint-previous-input 1) (previous-line 1))
  (lambda nil (interactive) (if (comint-after-pmark-p) (comint-previous-input 1) (previous-line 1)))()
  funcall-interactively((lambda nil (interactive) (if (comint-after-pmark-p) (comint-previous-input 1) (previous-line 1))))
  call-interactively((lambda nil (interactive) (if (comint-after-pmark-p) (comint-previous-input 1) (previous-line 1))) nil nil)
  command-execute((lambda nil (interactive) (if (comint-after-pmark-p) (comint-previous-input 1) (previous-line 1))))


  Thanks.

It looks like you've bound the arrow-keys to some command which causes
this error.  I don't see any similar command in Emacs sources (and I
don't get such an error in 'emacs -Q' with the normal arrow-key
commands).

   Sorry, there was a shell-mode-hook:

(add-hook 'shell-mode-hook
          '(lambda ()
             (local-set-key [home]        ; move to beginning of line, after pro
mpt
                            'comint-bol)
             (local-set-key [up]          ; cycle backward through command histo
ry
                            '(lambda () (interactive)
                               (if (comint-after-pmark-p)
                                   (comint-previous-input 1)
                                 (previous-line 1))))
             (local-set-key [down]        ; cycle forward through command histor
y
                            '(lambda () (interactive)
                               (if (comint-after-pmark-p)
                                   (comint-next-input 1)
                                 (forward-line 1))))
             ))



    Is tnere a way to acnieve the navigation I seek?

    I've never had issues with this code before.

    Thanks.

That seems surprising since this problem is only fixed on the master
branch since February.

    Thanks for your  research.

    I have been switching back and forth between Emacs versions
    and it is possinle I got this error when not running master.

    I no longer have that session running so I can't double-check.

    I do see that it is working in a new Emacs session running
    master that was built today...

   Its mode-line contains:

          (Shell:no process Shell-Compile)

    Thanks.
