I strongly suspect the latter.

I'm not sure I agree that consistency is that important here. Casting
a quick glance at the 'ack' results, I see that "+Inf" is most often
used in symmetric contrast to "-Inf", and just "Inf" is used in ranges
and as the result of some overflowing computations. I think that makes
more sense than forcing the usage of one or the other.
