  # If the first argument to 'start' is quoted, then 'start' will create a new cmd.exe window with
  # that quoted string as the title. If the URL contained spaces, it would be quoted by subprocess,
  # and if we did 'start %1', it would create a new cmd.exe window with the URL as title instead of
  # actually launching the browser. Therefore, we must pass a dummy quoted first argument for start
  # to interpret as the title. For this purpose, we use the empty string, which will be quoted
  # as "". See #9253 for details.
