It is not a bad question, but I can't remember now. Whatever I try to do
I get an ending slash there (unless I do not set default-directory
myself of course). However I am quite sure I did not get that before.
Something must be different ...

The value of default-directory on w32 may still use \ instead of /. That
is the case after "emacs -Q", but that is another problem.
