I agree the current situation is not satisfactory, but I also think TAB
or S-TAB should never, ever, move point. For example, I use S-TAB to get
a quick overview of the structure of the document.

I fixed this by making TAB show more when called from an invisible part
of the buffer.

Thank you for the report.
