    Of course, the filename part would be determined just as it is now (using
    the --dired data if available, for example).

Ok, you're right about that part.  When using --dired, we would
still reliably find the filename.  But finding where to insert extra
spaces would not be entirely reliable, just as finding the file name
was not entirely reliable in the past.
