It would be a bad idea to use 'start' on Windows: it has too many
quirks regarding quoting of its command line.  Instead, just invoke
the existing primitive w32-shell-execute with the 'open' verb.  As a
nice side effect, this will support Unicode file names, something that
is currently impossible when you invoke an external command.
