It doesn't involve starting another program (either cmd.exe or 'start'
itself), and it works equally well on all versions of Windows, whereas
'start' changed its behavior at least twice.

But if we want to invoke a shell command, then I guess 'start' would
be fine.  Juts remember that dired-shell-stuff-it invokes 'start' as
well.
