[Bug libc/10699] New: The argz create routines respond differently to empty strings

["lucien at haijen dot be" <sourceware-bugzilla at sourceware dot org>]

argv arguments can be empty strings by specifying '' or similar.
Those empty strings are part of argz as created by argz_create().
However argz strings created by argz_create_sep() does not allow empty
strings ; they are simply ignored thus producing a argz that cannnot be
used (after some processing) to a new argv array.
