Looks good.

Simplified spoken, this code makes Tramp work. If you call for example
(directory-empty-p "/sudo::/") , find-file-name-handler (the ELisp
equivalent to Ffind_file_name_handler) checks, whether Tramp feels
responsible for this directory name, and it calls Tramp's function in
case.

You know, that your function cannot handle "/sudo::/".

Tramp file name syntax here. See (info "(elisp) Magic File Names")

Best regards, Michael.
