Me too.  If I had to guess about why, I think I would say (1) being
used to it from the original K&R, and (2) it's philosophically
consistent with how if(), for(), while(), and logical expressions
work.  Speaking for myself that consistency is worth a lot, and
using NULL sticks out like a sore thumb.
