I can confirm this. Tested with recent Emacs 29.0.50. As far as Tramp is
concerned, I see
--8<---------------cut here---------------start------------->8---
1 -> (file-name-all-completions "" #("/sudo:root@gandalf:/root/" 6 10
(tramp-default t) 11 18 (tramp-default t)))
1 <- file-name-all-completions: (".tcshrc" ".bash_profile" ".viminfo" ".cshrc"
"tmp/" "../" ".cache/" ".local/" ".tramp_history" ".bash_history"
"anaconda-ks.cfg" "./" ".bashrc" ".history" ".emacs.d/" ".config/"
".bash_logout" ".dbus/" ".ssh/")
--8<---------------cut here---------------end--------------->8---
This looks proper. However, when clicking on "tmp/" (as said in your
recipe), I get "/sudo::~tmp/".
I'm not an expert in the completion machinery, so I cannot contribute
much more to this problem.
Best regards, Michael.
