[boost] program_options suggestion

I really like program_options from Vladimir Prus.  Thanks for adding
bool_switch!

One suggestion.  We now have bool_switch, so a variable can default to off,
and turn on with --option (without having to say --option=true).

How about begin able to say --no-option to turn it off?  This would make the
interface consistent with gnu standards.  If it's not too difficult it
would make a good addition.
