bug#27980: disabled-command-function should accept ^G

[積丹尼 Dan Jacobson]

disabled-command-function is an autoloaded compiled Lisp function in
‘novice.el’.

It prompts with

     (message "Type y, n, ! or SPC (the space bar): ")

However in 99% of the cases, the user has triggered it by mistake,
and wishes to get out with ^G, and not be bothered to read the details.

However ^G is disabled here.

Repeated hitting of it will not get one out and back to editing.

I vote ^G be mapped to "n", and be listed in the message.

Reading those details i discovered several very useful disabled commands;
i enable some of them in my init file at startup.

For me C-g it works:
emacs -Q ~
a ; `dired-find-alternate-file' (disabled by default)
;; Appear the message.
C-g ; The message is gone; the command was canceled.

OK ^G is working again for me now.

Well my only request now is ^G should be listed along with the rest of the keys.

Well, C-g is somehow an universal way of cancel whatever interactive 
command.  It's assumed that any kind of prompt can be safely canceled with C-g.
That is  from lesson #1 in Emacs; i don't think we need to mention it in 
every prompt.
