Hello Yidong,
The other day I was going to fix all the delete-backward-char warnings
in Emacs but didn't finish it because I encountered things like
backward-delete-char-untabify and it does make the code a bit more
difficult to read with the extra ().
I wonder whether defining a compiler macro will be much easier and
less pain. Preliminarily something like:
,----
| (require 'cl)
| (define-compiler-macro delete-backward-char (n &optional killflag)
| `(delete-char (- ,n) ,killflag))
`----
And we can continue using the current doc string in delete-backward-char
to warn users about its future uses.
Just a thought.
HTH,
Leo
