No problem. My main job as Tramp maintainer is to explain other people
their configuration :-)

GNU ls has changed its default how to quote special characters in file
names. Likely, you've got a recent version of coreutils on your machine.

This change has raised controversioal discussions, but now it
exists. See <https://www.gnu.org/software/coreutils/quotes.html>.

"-N" isn't a default ls option. It doesn't work on my QNAP NAS, for
example (being busybox ls there). See
<https://pubs.opengroup.org/onlinepubs/009696899/utilities/ls.html> for
POSIX conform ls arguments.
