Help page for empty strings is weird.

[h-2]

For empty strings, the help page looks like this:

    --data-path2 (std::string)
          Default: .

This makes it look like the default is "." when in fact it is "". I would suggest that the empty string be formatted as "". In fact, I would suggest that all strings are quoted here, otherwise a default value of . will be printed as ...

I agree that we should quote the strings, it looks a bit weird.

For now, you can add .default_message = "\"\"" to the config.
