RE: default-directory in minibuffer on MS Windows

    Can you specify more rigorously when does `default-directory' use
    backslashes for you?  I only see it in *scratch*; everywhere else I
    tried `default-directory' has forward slashes.

    It's hard to try to find the reason(s) for this without knowing where
    to look.

1. emacs -q

2. Do this or similar:

(setq pop-up-frames t)
(defvar my-minibuffer-frame-alist
  (append '((minibuffer . only)) minibuffer-frame-alist))

(defvar my-minibuffer-frame (make-frame my-minibuffer-frame-alist))

3. In the standalone minibuffer frame, do `C-x 4 f'.

Actually, I suspect that the problem might occur not only in a standalone
minibuffer and *scratch*, but also in any buffer that is not associated with
a file or that otherwise doesn't know a good directory to use. I'm not sure
of that, but it seems to be true - *Messages*, for instance.

In any case, I can systematically reproduce it with the instructions above,
or by just emacs -q, going to the *scratch* buffer, and doing `C-x 4 f' (as
you mentioned).

Thanks,
