[resending after learning about unarchive…]

Hi Eli et al.,

I enabled kill-ring-deindent-mode when I saw it in the Emacs 30 NEWS,
but it didn’t seem to work. Recently I came back to it and determined
the root cause after some debugging and found this bug.

Would you mind cherry-picking the fix to emacs-30? I “backported” it in
my config via advice and it works as advertised.
