It's not the UNPK instruction that suffers the S0C7, but any
packed-decimal instruction (except ZAP with a packed-decimal source
field). UNPK just "expands" each nybble but the rightmost byte into a
byte, and inserts a "sign nybble" of x'F'; and just reverses the order
of the nybbles in the rigntmost byte of the field being unpacked. It
can suffer a S0C4 and perhaps other interruptions, but not a S0C7.
