It turns out that `string split0` didn't actually ever do any splitting. The arg_iterator_t already split stdin on NUL, and split0 just performed an additional search that could never succeed (since arguments from argv already can't contain NUL). Let the arg_iterator_t not perform any splitting if asked, and then let split0 split in 0. One slight wart is that split0 ignores a trailing NUL, which normal split doesn't. Fixes #5701.
