bug#70914: 29.3; Crashes often on Windows

[Simen Endsjø]

Here's some output when printing filenames in get_volume_info. I've tried
searching around and reading code, but I haven't found out where
"d:/profiles/%s" or "//" comes from.

    get_volume_info:
name="d:/.emacs.d/.local/straight/build-29.3/org-fancy-priorities/org-fancy-priorities.dll"
    get_volume_info:
name="d:/.emacs.d/.local/straight/build-29.3/org-fancy-priorities/org-fancy-priorities.dll.gz"
    get_volume_info:
name="d:/.emacs.d/.local/straight/build-29.3/org-fancy-priorities/org-fancy-priorities.elc"
    get_volume_info:
name="d:/.emacs.d/.local/straight/build-29.3/org-fancy-priorities/org-fancy-priorities.elc"
    get_volume_info:
name="d:/.emacs.d/.local/straight/build-29.3/org-fancy-priorities/org-fancy-priorities.elc"
    get_volume_info:
name="d:/.emacs.d/.local/straight/build-29.3/org-fancy-priorities/org-fancy-priorities.el"
    get_volume_info:
name="d:/.emacs.d/.local/straight/build-29.3/org-fancy-priorities/org-fancy-priorities.elc"
    get_volume_info: name="c:/Users/simend/.ssh/id_rsa"
    get_volume_info: name="d:/profiles/%s"
    get_volume_info: name="//"
