I initially thought about it but changed my mind for +/- 0xc0 that
covered the same cases in my opinion. Do you have a particular error
case in mind that would be caught by this one that the other one does
not catch ? I'm fine for proposing a respin of the patch to improve
it if it brings some value, but I'm still failing to figure when that
would be the case.

Thanks,
Willy
