That's exactly the kind of problem why I have CC'd you.

Is this a documented feature, however?  Heard about it (from you).  But
`dired-noselect' doesn't seem to handle or support this case at all, at
least not specifically, although the code doesn't error in this case.

I can only find places in the documentation where the car is described
or referred to as "directory name".

Could you please briefly refresh my knowledge about this use case?  Does
Vanilla Emacs somewhere make use of this case?

Hmm, indeed, this works in -Q.  Seems one of my local hacks broke this
case.


Thx,

Michael.
