There's something very odd going on here.
If I create a file /tmp/bar and then say
(make-symbolic-link "bar" "foo")
I get, as expected
-rw-r--r-- 1 larsi wheel 0 Aug 4 14:09 bar
lrwxr-xr-x 1 larsi wheel 3 Aug 4 14:09 foo -> bar
However, if I do something similar in the test director, dired insists
on adding a "@" to the end of the file name, which messes up everything:
/var/folders/l6/0kf2px5j7tz_wbp9lf_hgfwm0000gn/T/test-dir-iRvcaN:
-rw-r--r-- 1 larsi staff 1 Aug 4 14:12 zot
lrwxr-xr-x 1 larsi staff 3 Aug 4 14:14 zotlink@ -> zot
Uhm... Oh, that's the entire point of the test. :-) "ls -F" adds the
"@".
So the error is a real bug, because
(dired-get-filename 'no-dir t)
=> "zotlink@"
And that's because dired-ls-F-marks-symlinks is nil...
;; 1. For dired to work on a host which marks symlinks with a trailing @ in
;; an ls -alF listing, you need to (setq dired-ls-F-marks-symlinks t).
;; Most UNIX systems do not do this, but ULTRIX does.
And Macos is another:
larsi <at> space /tmp % ls -alF /tmp/
total 0
drwxrwxrwt 8 root wheel 256 Aug 4 14:12 ./
drwxr-xr-x 6 root wheel 192 Aug 2 18:53 ../
-rw-r--r-- 1 larsi wheel 0 Aug 4 14:09 bar
lrwxr-xr-x 1 larsi wheel 3 Aug 4 14:09 foo@ -> bar
lrwxr-xr-x 1 larsi wheel 3 Aug 4 14:10 foo3@ -> bar
lrwxr-xr-x 1 larsi wheel 3 Aug 4 14:12 foo4@ -> bar
OK, I've now adjusted the test and fixed the doc string to
dired-ls-F-marks-symlinks in Emacs 28.

Ah, this explains why the test wasnʼt failing for me: I installed GNU
ls :-)

And I didn't quite fix it, either... I thought I did, but because of
that defun/ert-deftest thing, I didn't actually check it.
There seems to be further bugs with dired-ls-F-marks-symlinks -- it
doesn't work when in editing mode...

The bug is in wdired--restore-dired-filename-prop, which calculates the
end of the file name wrong in this case.

OK; think I've got it now...
I really dislike how dired (and wdired) works -- it's just hack upon
hack...
