Java does negative characters, but it doesn't do negative groups. [^(abc)] should be anything except the string "abc."

Thanks again, the multiline test was failing without (?s). I had it buried where it wasn't easily seen. I changed my tests to be more visual and added them to the gist.

Still not sure where "negative groups" is coming from - I've not heard that term, nor seen the syntax [^(abc)] except as a negative character class (any char except those five) - not in Java/Python/Perl/PCRE or any others I'm aware of. Have you got a reference for it?

I don't have a reference offhand. Perhaps it's something floating in my brain from formal languages. It'd be rather handy. I know this isn't the first time I've tried to use it.
