Come on guys, why so mum about the fact that one cannot turn off the
special effects of ! and ^ when running M-x shell?
It is quite disturbing for one who has turned them off years ago in
bash (set +o histexpand) to suddenly have them play tricks on one in
M-x shell.

Because I have no idea what you're talking about. You should know how to submit
a proper bug report by now.

Isn't your shell initialization file read, even under `M-x shell'?
If not, is this the effect you want:
(add-hook 'shell-mode-hook
(lambda ()
(local-set-key "!" 'keyboard-quit)
(local-set-key "^" 'keyboard-quit)))

Only proper bugs deserve proper bug reports. <--original witty phrase debuting here
I'm talking about [*info* (emacs) History References]
$ emacs --no-site-file -q -nw -f shell
c a t RET ! ^ ! ^ ! ^ ! RET ESC p
One sees
$ cat
!^!^!^!
!^!^!^!
!
It has mangled my last line. I want the three lines to look the same.

To be clear, in my above example, I am not talking to the shell
anymore, but to cat. So don't bash bash. shell-mode is to blame.

no, you're barfing up the wrong tree. The shell-mode author thought
csh-style ! and ^ history substitutions were so great, he forgot to
leave a way to turn them off. Yes, not being able to type them would
indeed fix the problem, as would snipping my keyboard cable. "rm -r
dangerous??, just local-set-key "r"...

C-h v comint-input-autoexpand
Does setting that variable to nil in a shell-mod-hook function fix your problem?

Hmm, I already had
(add-hook 'comint-mode-hook
(function (lambda ()(setq comint-input-autoexpand nil)))) ;no more "!" surprizes
OK, now I will add
(add-hook 'shell-mode-hook
(function (lambda ()(setq comint-input-autoexpand nil)))) ;no more "!" surprizes
for double protection. Thanks.
Blame
-----
Blame for my troubles can be conveniently shifted onto the Info page for saying
Shell mode can optionally expand history references in the buffer
when you send them to the shell. To request this, set the variable
`comint-input-autoexpand' to `input'. You can make <SPC> perform
history expansion by binding <SPC> to the command `comint-magic-space'.
It said 'optionally' when indeed it is doing it somewhat already by default.
Odd, in the source it says
(defcustom comint-input-autoexpand nil
But when I do
$ LC_ALL=C emacs --no-site-file -q -nw -f shell
and check its value, it is 'history.
Yes, I wish it was history, as in out of here :-)
