#622 closed proposed feature (fixed)

make leading ideals automatically inherit the "isSB" attribute

I hope it won't break existing code, but I would like the output of "lead()" to inherit the isSB attribute, so that I don't need to set it manually when trying to suppress the "<ideal> is no standard basis" warning.
