Hi,
thanks for the hint.
However don't think customizing DEL does it.
In most cases you will use DEL as `untabify'.
"Hungry" eates a lot - that's is fine, but not as taking the common DEL.
Therefore think a seperate key for hungry-delete is needed.
However, seems it must not be copied from the scratch.
What about such a thing:
(defun hunry-delete (&optional killp)
"Delete characters backward, changing tabs into spaces.
Kill (save in kill ring) if KILLP is non-nil.
"
(interactive "P")
(let ((backward-delete-char-untabify-method 'all))
(backward-delete-char-untabify 1 killp)))
