Is that manual page incorrect?
I would think that
strsep() returns NULL when *stringp points to '\0' character
and that if delim is not found in stringp then stringp is just advanced to '\0' character of string (and original *stringp value is returned)
If that is not true, then these all patches are incorrect. Namely last token will be skipped.
