How common is it to have all of negative, zero, and positive counter values in the same list? As far as I can tell, it’s uncommon enough (less than negative counter values in general, which are not common themselves) that we shouldn’t bother making it pretty. (This is a feeling based on zero data, though.) -- Simon Sapin
