Detail:
  There's some questionable code in DoSwi[Sector]DiscOp[64] where it calls
  PollChange in an apparent attempt to support the ADFS floppy state machine.
  In the no-card-detect SDFS case, we can detect from a card's state whether
  it has been changed or not; to be able to signal this to software that
  cares about such things, we increment the sequence number late in the
  process. The downside is that when the card *has* changed, two consecutive
  PollChanged calls will differ from the steady state: the first because
  MaybeChanged is signalled, the second because the sequence number
  mismatches. DetermineDiscType didn't handle this gracefully, ending up
  pointing off the internal array of disc records, resulting in a string of
  gibberish when canonicalising a drive-based file spec. Fixed by having
  DetermineDiscType double-check that the drive is not empty.

  Fixed UpCall_MediaNotPresent and UpCall_MediaNotKnown to actually use the
  media type string from MiscOp 4. For example, you'll now see "Please insert
  card 'RISCOSpi'" being generated by the Wimp under SDFS.

  Improved documentation of MiscOps 4 and 5.
