bug#38818: Dired: mention deleting buffers, not just windows

[積丹尼 Dan Jacobson]

Yup, confirmation when edited or marks sounds good.

Otherwise if the user really wanted to keep the buffer around, he could
just do C-x C-b to switch to another buffer.

Wait, looking at C-h b,

i               dired-maybe-insert-subdir
j               dired-goto-file
k               dired-do-kill-lines
l               dired-do-redisplay
m               dired-mark
n               dired-next-line
o               dired-find-file-other-window
p               dired-previous-line
q               quit-window
s               dired-sort-toggle-or-edit
t               dired-toggle-marks
u               dired-unmark
v               dired-view-file
w               dired-copy-filename-as-kill
x               dired-do-flagged-delete
y               dired-show-file-type

So we "see" the problem is caused by just reusing quit-window instead of a
more tailored dired command...

One also notices
  dired-clean-up-buffers-too is a variable defined in ‘dired-x.el’.

So previously people had been working on related problems, but never got
around to all the left over directories.

Actually I don't know how to bind kill-buffer to q and not have it still
ask me which buffer, but just kill it (marks and all, for now I guess.)
I'm not a lisp wiz.
