* Make the HW-specific get_unique_id switch pretty
* Prepare to field-test by whitelisting all known fibre array, try to
fetch WWID from the standard EVPD 0x83 off 8 for everyone ... we will
learn from feedback :)

Could you drop a note with the udev-009 release-notes asking for testing
this WWID fetching thing ?
