This never was intended to be happening.  The values to be passed to
argz_stringify are supposed to come from other argz_* functions and
those are always counting in the trailing NUL byte of the last
element.  But since it's easy to do I've aptched the argz_stringify
code in glibc to allow this case as well.  It might be useful for some
purposes (like stringifying only parts of an argz value).
