Overriding a user option in this way is not something we do, or should
do.  The user settings should be honored.

Why is it a problem not to override that option, when its default
value will cause the buttons to be shown in Help buffers?  Put it
another way: why should we consider Help buffers under Outline Minor
mode be any different from any other buffer under that mode?
