bug#36610: [PATCH] Make finder-exit use quit-window

[Stefan Kangas]

When I have two windows open and hit C-h p to open finder, then press q to exit,
the second window is suddenly gone.  This is because finder-exit uses
kill-window instead of quit-window, and is a minor annoyance.

The attached patch fixes that by using quit-window instead.

(I'll send the patch in a separate message once this is assigned a bug
number.)

Thanks,
Stefan Kangas
