bug#5668: 23.1.93; comint-mode-map key definitions for [delete] and [kp-

This bug report will be sent to the Free Software Foundation,

not to your local site managers!

Please write in English if possible, because the Emacs maintainers

usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,

and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug

and the precise symptoms of the bug. If you can, give

a recipe starting from `emacs -Q':

In comint.el, the following key definitions have been added to

comint-mode-map:

;; The following two are standardly aliased to C-d,

;; but they should never do EOF, just delete.

(define-key map [delete] 'delete-char)

(define-key map [kp-delete] 'delete-char)

Now, I understand the motivation here BUT, typically, one only defines

mode-specific C-c bindings and mode-specific pull-down menu

bindings in mode maps. In my case, I have delete and kp-delete assigned

to perform an entirely different function. This is the first time any

mode map has ever usurped my custom assignments to the delete and kp-delete

keys. In addition, the above reassignment assumes the user is using a PC

type of keyboard. If one is using a DEC VT series keyboard, or a DEC VT

terminal series emulator, then the Delete key is located where the PC

Backspace key is located. In this case, the Delete key assignment in

the global-map will be to DEL, not C-d.

A better approach is NOT to make these assignments unilaterally.

Instead, the code should examine the current key assignment for delete

and kp-delete in current-global-map. ONLY IF the current assignment is

"C-d" should the above redefinitions be made.

If Emacs crashed, and you have the Emacs process in the gdb debugger,

please include the output from the following gdb commands:

`bt full' and `xbacktrace'.
