I told yesterday in response to another message of yours how can you
see the changes in the repository using  Web browser.  Please take a
look, then we can discuss the fix.

No, the real problem is that the reference to help-window-setup gave
you wrong expectations regarding what information that function should
add.  My change tried to make those expectations match the original
intent.

That's a subroutine, so I don't necessarily see its doc string as
something we need to invest an effort in.
