This still happens.

Well, we're speaking about tramp-sh-handle-insert-directory. This does
the following:

- Check, whether the remote ls command supports "--quoting-style=literal
  --show-control-chars" or "-w" (for *BSD). If yes, add this to SWITCHES.

- Check, whether the remote ls command supports "--dired". If not, remove
  "--dired" from SWITCHES.

It doesn't know anything about "-N". So I propose to remove "-N" from
switches unconditionally in Tramp.

Best regards, Michael.
