I think that the majority of the issues here are caused by the fact that the man pages are out of date.
@idank You've stated in other issues that you'd like to eventually change the input from man pages to something else.
Is there a plan somewhere? Is this something you'd be willing to accept support with?
I'd love to get things to a place where it would be easier to keep the underlying data updated!
On a side-note, I'm crazy enough to go through all the issues and provide you with a list of issues that are caused by out-of-date man pages, if you'd want it.
