Keeping everything as is just with HelpText.AdditionalNewLineAfterOption = false

I would like to keep everything as is just have the additional newlines removed in the help output. I have been trying to achieve this for one hour now, but when I create my own parser with `new Parser(with => with.HelpWriter = null)` and try to display help myself, it won't work with custom help for custom commands, i.e. `myapp help add` will no longer print the specific help for the add command.

So how can I just get rid of those additional newlines in the help screens and keep everything else as it is? Is it possible at all?
