Unfortunately, the terms "natural numbers" is ambiguous enough that the
Wikipedia page about them states very early :
--8<---------------cut here---------------start------------->8---
Some authors begin the natural numbers with 0, corresponding to the
non-negative integers 0, 1, 2, 3, …, whereas others start with 1,
corresponding to the positive integers 1, 2, 3, ….[1][2][3][4] Texts
that exclude zero from the natural numbers sometimes refer to the
natural numbers together with zero as the whole numbers, but in other
writings, that term is used instead for the integers (including
negative integers).
--8<---------------cut here---------------end--------------->8---
(https://en.wikipedia.org/w/index.php?title=Natural_number&oldid=705339412)

Now if you look at the German version, you'll see the first list omits
0, and only afterwards they mention 0 can be included too.
--8<---------------cut here---------------start------------->8---
Die natürlichen Zahlen sind die beim Zählen verwendeten Zahlen 1, 2, 3,
4, 5, 6, 7, 8, 9, 10 usw. Oft wird auch die 0 (Null) zu den natürlichen
Zahlen gerechnet.

Anyway, this has only limited implications IMHO : the docstring should
be explicit about what the function does, including which convention of
"positive" or "natural number" it follows (maybe also referencing natnump
from the docstring of plusp).
