--line-regexp option with null data

[Steven Penny <svnpenn@gmail.com>]

Consider this command:

    printf 'alpha\nbravo\ncharlie\n' | grep --line-regexp --quiet bravo

grep sees 3 lines separated by newline, and matches the bravo line. Now consider
this command:

    printf 'alpha\0bravo\0charlie\0' | grep --line-regexp --quiet bravo

My thinking tells me that because I have not used `--null-data`, grep should see
1 or even 0 lines separated by newline, and fail to match a `bravo` followed by
newline. However it does not, it succeeds just like the first command, why is
this?

Note I also tried this on Debian with Grep 2.2 and it works as expected.
