When I collapse or expand a fold I would expect the fold position on the
screen and the cursor position to remain the same, with the contents of the
fold rolling up or down from that position.
This is so I can collapse and expand by successive clicks in the same
This works fine at the begining sections of a file. However if the
collapsing would move the end of the file up on the screen, it instead moves
the fold down. This means I have to move the mouse after collapsing in order
to expand the same fold.
I hope this is a valid enhancement request.
