FWIW, "natural number", like "whole number", unfortunately
has two different meanings, 1... and 0..., depending on
who is talking.

https://en.wikipedia.org/wiki/Natural_number

Emacs has predicate `natnump', with alias `wholenump',
meaning 0...  So the doc for a defcustom type that
mentions "natural number" had better make clear which is
meant.  It can do that by mentioning predicate `natnump'.
