I believe it is wrong to expand wilcards in `insert-directory'. It is
not designed for that. Expanding must happen in
`dired-insert-directory', which calls then `insert-directory' for the
results.
Hi Michael,

thank you for your advice on this.  I have a new version which handle the
expansion in `dired-insert-directory'.  I pushed a new branch with
the newest patch:
origin/feature/dired-wildcard-in-dir-bug#27631

When the user is neither using 'ls-lisp' nor 'eshell-ls', then we run in the remote host something like:
(process-file "/bin/sh" nil (current-buffer) nil "-c" (format "ls %s %s" 
switches wildcard)))

I have tested it running tramp in a remote machine and it seems to work.
What do you think?
