If someone writes a patch to make everywhere <null> and changes this page
in the process I wouldn't complain. For now there is no such standard, we
use empty string everywhere else, and that isn't a good choice here IMO.
It is probably a good choice for elsewhere since the empty string is our
default. While specific to this page \N reads the best for these examples
IMO. But I'll concede to whatever if others think this choice is a
review/commit blocker.
