Hmm, maybe we should be using File::Copy::move() instead of rename(). The docco for that says:

        If possible, move() will simply rename the file. Otherwise, it
        copies the file to the new location and deletes the original. If an
        error occurs during this copy-and-delete process, you may be left
        with a (possibly partial) copy of the file under the destination
        name.

Unfortunately, I've stumbled upon inability of File::Copy::move()
to move directories across filesystems, exactly as described here:
https://stackoverflow.com/questions/17628039/filecopy-move-directories-accross-drives-in-windows-not-working

(I'm sorry for not looking above rename() where this stated explicitly:
# On Windows use the short location to avoid path length issues.
# Elsewhere use $tempdir to avoid file system boundary issues with moving.
So this issue affects Windows only.)

Best regards,
Alexander
