>Organization:
	Dis-
>Environment:
	Noticed on 5.2/amd64.  Also found on 9.1/amd64.  cvsweb
	indicates present in -current as of 2024-03-21, sysconf.3
	version 1.52.
>Description:
	sysconf(3) describes _SC_PASS_MAX as "The maximum length of the
	password, not counting NULL.".  But NULL is semantic nonsense
	there; it should be "NUL", or possibly "null".  (Confusion like
	this is one reason I believe NULL should never be used; see
	http://ftp.rodents-montreal.org/mouse/blah/2009-10-09-1.html
	for more, including other reasons.)
>How-To-Repeat:
	Read sysconf(3).  Notice the semantic inconsistency.
>Fix:
	-The maximum length of the password, not counting
	-.Dv NULL .
	+The maximum length of the password, not counting the terminating NUL.
