Amen!

It also makes a non-empty set of programs *correct*.

However, correctness aside, it is good to use NULL for null pointers,
for the same reason it is good to use "hello, world" rather than
{ 'h', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd' }
to initialize arrays of characters.

(One point extra credit for spotting the difference, two points
extra credit for spotting the case where the two are not different.)
