Otherwise return NULL. (/nullptr. Apparently we are updating the style guide to
say to use nullptr instead of NULL. I have mixed feelings about using NULL some
places and nullptr elsewhere; maybe someone will do a search and replace...)

Updating the comment.  I share your mixed feelings.  Let me know if I'm wrong,
but I'd like to keep using NULL for consistency until the find and replace
happens.
