Fix inconsistency in ARRAY_SIZE(NULL) documentation (#3198)
This PR fixes the inconsistency between the description and example
for ARRAY_SIZE(NULL) reported in #3073.
I did not receive a response on the issue, so I aligned the description
with the example behavior. Please let me know if a different wording
is preferred.
