When buffer of recursive edit is killed, recursive edit remains still
not finished, and expected outcome for me as user is that recursive edit
get aborted.

See reference by Gregory:
https://lists.gnu.org/archive/html/bug-gnu-emacs/2022-12/msg02096.html

One can reproduce it with following procedure:

1. Invoke (read-string-from-buffer "Edit #1" "My string")

2. Press C-x k to kill the buffer

3. Observe in the modeline that there are square brackets indicating
   that recursive edit is still going on.

4. To finalize those ghost recursive edits one can press C-M-c

My expectation for C-x k is to abort recursive edit, and not keep
function in memory waiting for C-M-c

I am using many times recursive-edits to edit description, text, values
in the database. Video is here:
https://gnu.support/images/tmp/2022-12-23/2022-12-23-07:56:46.ogv

My actual program is following:

I have used back in time temporary files from console to edit database
values. But then a program would write string to temporary file, invoke
the editor, and know that editor finished its work, then program would
read the string back into the database from temporary file.

If I use Emacs to fetch database value, I could edit it nicely in the
same manner provided I use external editor. And that makes not much
sense.

For that reason I use recursive-edits. When recursive edit is finished,
the returning string is recorded in the database as recursive-edit
remains with the running function waiting for input. Recursive edit
buffer closes when finished, and that is signal that string is finished
and shall go into the database.

If I use ordinary file editing, it is unclear for invoking function when
is that editing really finished. Or maybe I should add hook and replace
buffer killing function C-x k with the function to load the saved file
of the buffer back into the database?

Any idea is appreciated.
