I hacked on it for a bit and came up with the attached proposed patches 
to the emacs-29 branch. I have not installed them.

These patches address the issues raised by Michael by passing only 
single arguments to make-directory handlers. That way, we don't need to 
worry about whether the handlers follow the new convention. At our 
leisure, perhaps in Emacs 30, we can upgrade the make-directory handlers 
to support the new convention.
