Indeed there is other problems, like Michael mentionned but also Eli.

I had also problems with `wdired-get-filename` which at the end use
(concat dir file) instead of (expand-file-name file dir).
If filename is absolute we endup with
e.g. "/home/you/tmp//home/you/tmp/foo.txt" instead of
"/home/you/tmp/foo.txt".
Curiously this happen in emacs-28 but not in 29 (why I submitted no
patch for this).

Great thanks.
