@ -5842,7 +5842,13 @@ Can be `untabify' -- turn a tab to many spaces, then delete one space;
(defun backward-delete-char-untabify (arg &optional killp)
"Delete characters backward, changing tabs into spaces.
The exact behavior depends on `backward-delete-char-untabify-method'.
Delete ARG chars, and kill (save in kill ring) if KILLP is non-nil.
If Transient Mark mode is enabled, the mark is active, and ARG is 1,
delete the text in the region and deactivate the mark instead.
To disable this, set option ‘delete-active-region’ to nil.
Interactively, ARG is the prefix arg (default 1)
and KILLP is t if a prefix arg was specified."
