Garrett quoted an addendum to the standard that says id *DOES* include
the trailing NUL.  But he didn't post it to the list:

{PATH_MAX}
        IEEE PASC Interpretation 1003.1 #15 addressed the
        inconsistency in the standard with the definition of path name
        and the description of {PATH_MAX}, allowing application
        writers to allocate either {PATH_MAX} or {PATH_MAX}+1
        bytes. The inconsistency has been removed by correction to the
        {PATH_MAX} definition to include the null character. With this
        change, applications that previously allocated {PATH_MAX}
        bytes will continue to succeed.
