... on the other hand, I have just noticed, that in those testfiles, there are
only VERIFY with > 0 and < 0, no strict comparisons with +1 and -1.

What do you prefer:
1- (more strict) Changing all the > 0 to == +1 and all < 0 to == -1.
2- (less strict) Use in my changes too < 0 and > 0.

??

Ciao, Paolo.
