pcre2grep should have an option to null-terminate filenames output with --files-with-matches and --files-without-match options

GNU grep has -Z and --null. git grep has -z and --null. However, neither support multiline PCRE matching.

I wanted to use this to detect files that don't end in a final newline, and pipe that into another command to remedy the situation.

Previously, my script only removed trailing whitespace and optionally replaced tabs with spaces, so git grep did the trick. The script is able to handle arbitrary filenames, and I'd like it to stay that way.

This should be straightforward to implement, and I will look into it once I have got some other work out of the way.

I have just committed a patch that implements -Z aka --null. It is intended to be much the same as GNU grep.
