Hello,

a fix was committed. In the case when a new interrupt is added and 
PendingInterruptCount was already <0, a call to CycInt_UpdateInterrupt() 
is also made, which prevents loosing a pending interrupt (loosing an 
internal HBL interrupt in Hatari could eventually cause a crash, as seen 
in the talktalk2 demo).

Hopefully, this should not create regressions in other cases.
