* Support --version on non-UNX, too.

* Consistently show the first unknown option and the help blob in the presence
  of any unknown options.

* There is no need to tunnel --help/--version past oosplash in the soffice
  script, as oosplash is prepared to treat them adequately (esp. not pass them
  over any pipe); this only added unnecessary variance to what spellings exactly
  are supported and how mixtures of --help, --version, and unknown options are
  handled.
