1. Is it possible to expand --help so that it also gives the default values of options? Obviously, it's not likely to tell defaults that it doesn't no about, but at least the ones specified by default_value()?
I need to think about it. The biggest issue I see that that it would mean that if you have option of type T then T would be required to have operator<<, which might be too severe limitation.
2. What was the resolution to the earlier problem of confusing a negative parameter value with an option?
I think I've fixed that. See the attached.

It's a small point, but here's my opinion. You say something like: "If option requires a value and following -<number> doesn't match an option, then parse it as an argument". I would suggest "If option requires a value then parse *any* following string, including -<number> as a value, unconditionally".
