(defvar my-map nil "...")
(define-prefix-command 'my-map)
(define-key my-map (kbd "a") 'forward-char)
(define-key my-map (kbd "b") 'backward-char)
This is OK:
(define-key global-map (kbd "C-n") 'my-map)
These are not OK:
1. (define-key global-map [remap next-line] my-map)
2. (define-key global-map [remap next-line] 'my-map)
Using `C-n' (normally bound to `next-line') raises an
error saying that the keymap (for #1) or the keymap
variable (for #2) is not a command (`commandp').
Apparently the handling of pseudo function-key `remap'
doesn't cover this case. Shouldn't it be able to?
Same thing if you use, say, one of these instead of
`define-prefix-command':
(fset 'my-map my-map)
(fset 'my-map 'my-map)
Apparently the problem isn't the definition of the
keymap for the prefix key. And it isn't because
`define-key' can't handle a `symbol-function' value
that's a keymap or a symbol whose `symbol-value' is
a keymap (it can).
The problem seems to be only with the way the
[remap COMMAND] is handled by `define-key' (and by
`global-set-key' etc.).
Is it feasible to have this case handled too?
