bug#54331: 27.2; Closing frames loaded from desktop-read

[Rehan Deen <rehan.deen@gmail.com>]

Huh, I have actually gotten used to `C-x C-c` simply closing the current
frame that I am viewing while in client-server/daemon mode. I am
prompted by the minibuffer on whether to save modified buffers --
including those not currently displayed in the frame I am closing -- but
after hitting `y` the single frame closes.

The help for `C-x C-c` says:
> C-x C-c runs the command save-buffers-kill-terminal ...

In "standalone" mode `C-x C-c` of course kills everything (after asking
to save changes in modified buffers).

Perhaps my daemon mode behavior is not standard. I am running this in
i3wm on Manjaro Linux if that helps. How does one "usually" close a
client frame? `C-x 5 0`, mapped to some shortcut?
