The extra whitespace was targeted at machine processing for a subset of users for a subset of runs of CLIs. On the other hand, there is a lot of concern over the extra verbose output. A user can set the help template for man, if desired. They can even do something (env? feature flag?) to make it only run when doing man generation. We also have #3174 in the works. So let's focus on the end-user reading `--help`. People wanting to use `help2man` have workarounds to do what they need. Fixes #3096
