I think it would better to follow the vim behavior here of having count starting from scrolloff point, otherwise 1gt would result in moving the screen by scrolloff.

But vim behavior here is good I think. If the screen is at the corner of the screen (0 or file end), 1H will go to the first line without scrolloff (same for the end), and if the screen is being scrolled to the middle, 1H will go to the first scrolloff position rather than the top. This is the nicer behavior but I think it is a bit more complicated to implement.

And with large scrolloff count it doesn't move the screen, so <n>H in vim won't change the screen in any bits, it will move to the last scrolloff point.

done, please take a another look


let last_line = view.last_line(doc);

let line = match align {
Align::Top => (view.offset.row + scrolloff),
Align::Center => (view.offset.row + (height / 2)),
Align::Bottom => last_line.saturating_sub(scrolloff),
// the last line might far above height, so use content middle if the view is not fulfilled
Align::Center => (view.offset.row + ((last_line - view.offset.row) / 2)),
// the last line might far above height, so se use last line if the view is not fulfilled
Align::Bottom => std::cmp::min(
last_line,
(view.offset.row + height - 1).saturating_sub(scrolloff),
),
}
.min(last_line.saturating_sub(scrolloff));
