And it tells us the truth™.

Your gls command returns the long listing of the file, although not
instructed via an "-l" option. I've compared it with gls on a FreeBSD
machine, which behaves as Tramp expects:

--8<---------------cut here---------------start------------->8---
% gls --version
ls (GNU coreutils) 9.1
% gls --color=never --quoting-style\=literal --show-control-chars --dired -d lisp
lisp
--8<---------------cut here---------------end--------------->8---

This seems to be a recent change.
<https://www.gnu.org/software/coreutils/manual/coreutils.html#What-information-is-listed>,
which is about coreutils 9.5, says:

--8<---------------cut here---------------start------------->8---
The --dired (-D) option implies long format output with hyperlinks
disabled, and takes precedence over previously specified output formats
or hyperlink mode.
--8<---------------cut here---------------end--------------->8---

OTOH, the coreutils 9.1 info manual on that machine claims

--8<---------------cut here---------------start------------->8---
The ‘--dired’ (‘-D’) option has well-defined behavior only when
long format is in effect and hyperlinks are disabled (e.g.,
‘--hyperlink=none’).
--8<---------------cut here---------------end--------------->8---

So I have to fix it in Tramp.

Best regards, Michael.
