> Calling "shell-command", "async-shell-command", or any other command
> calling "read-shell-command", globally sets the variable
> "comint-input-autoexpand" to 'history. "comint-input-autoexpand" is
> supposed to be a buffer-local variable with a default value of nil, and
> setting it globally can interfere with other shells that use the "!"
> symbol, e.g. the IPython shell.
>
> To reproduce, first "emacs -Q", then check that
> "comint-input-autoexpand" has value nil. Then type:
> "M-!", "echo foo", "RET".
> Then check that comint-input-autoexpand has been set to 'history.
