Paul's fix is very nice, I could not found it.

However, following case is not fixed yet.  Not only '.' but also hat
list (e.g. [^a]) should match newline with -z.  So we need clear
RE_HAT_LISTS_NOT_NEWLINE bit.

$ seq 2 | LC_ALL=C grep --null-data '[1-2][^a][1-2]'
1
2
$ seq 2 | LC_ALL=en_US.iso88591 grep --null-data '[1-2][^a][1-2]'
