patch 9.1.0414: Unable to leave long line with 'smoothscroll' and 'scrolloff'
Commit: https://github.com/vim/vim/commit/b32055e504ebd4f6183a93b92b08d61dad61c841

patch 9.1.0414: Unable to leave long line with 'smoothscroll' and 'scrolloff'
Problem: Unable to leave long line with 'smoothscroll' and 'scrolloff'.
Corrupted screen near the end of a long line with 'scrolloff'.
(Ernie Rael, after 9.1.0280)
Solution: Only correct cursor in case scroll_cursor_bot() was not itself
called to make the cursor visible. Avoid adjusting for
'scrolloff' beyond the text line height (Luuk van Baal)
fixes: #14726
closes: #14783
