Hi Daniel,
I have both good news and bad news.

The good news is that it's now possible to specify this flag via the public 
interface. Just

    command_line_parser(argc, avgv).allow_unregistered().run()

will do. The bad news is that my recent refactoring broke support for 
'allow_unregistered' inside command line parser. Really bad, especially given 
that I intended to add 'allow_unregistered' to the public interface as I did 
the changes. And we're in feature freeze mode now :-(

Doug, what's your opinion about my fixing the problem, despite feature freeze? 
Basically, there's public interface function that does not work at all, so it 
can be considered as bugfix, not as a new feature.
