Perhaps, but you do not have to look beyond this manual page to find
that such a practice, if it is even nominally applied, is not followed
consistently.   The remainder of the document spells the terminating
value as plain "NULL."  FreeBSD manual pages consistently refer to
NULL as a pointer value.

The Linux manual page spells the terminating value (char *)NULL and
explicitly documents why.  That is perhaps both pedantically correct
and clear.  I am amenable to such a change.

I observe simply that CheriBSD is not FreeBSD and that CHERI is an
exotic architecture.

Best,
