<delete> key exits Shell Mode (on Windows)

<delete> key exits Shell Mode (on Windows)

[Gareth Rees]

I'm running GNU Emacs 22.1.1 (i386-mingw-nt5.1.2600) of 2007-06-02 on 
Microsoft Windows XP.
My SHELL environment variable is set to "bash".

In a fresh emacs -q I type

M-x shell RET
<delete>

What I expect to happen: the bell should ring. (<delete> should delete 
the character after point, but point is at the end of the buffer so 
there is nothing to delete.)

What happens: the shell exits.

The reason for this is that <delete> is translated to C-d by 
`function-key-map' and in Shell Mode C-d is bound to 
`comint-delchar-or-maybe-eof'.

I suggest that <delete> and C-d be disunified in Shell Mode on Windows, 
and the former should be bound to `delete-char'.

(This was reported in July, but not very clearly; see
http://lists.gnu.org/archive/html/bug-gnu-emacs/2007-07/msg00210.html
I hope this report is better.)

I don't think Windows should be treated specially here. Although RMS
previously reported that he does not see the bug, that may be because
the key labeled "delete" is generating <deletechar> in emacs -nw on
GNU/Linux. Under X <delete> is produced, and the same bug is apparent.

You might want to try adding this to your .emacs and see if it
works better.
