CRUISE: Correct missing comma and extra value in Spanish font table.

The correction in 6046b8f1348a9a50ca09a257b5781a8ca2970d2d was not quite
correct as this was caused by a missing comma. This didn't cause a
compilation error as the code was still valid, just incorrect
 i.e. (0x80<newline>-1, gaves 0x7f).

This fixes bug #3568616 - "CRUISE: Cruise for a Corpse Spanish -
Incorrect character".
