Subject: vim-patch:8.2.4630: 'cursorline' not always updated with 'culopt' is
 "screenline"

Problem:    'cursorline' not always updated with 'cursorlineopt' is
            "screenline".
Solution:   Call check_redraw_cursorline() more often. (closes vim/vim#10013)
https://github.com/vim/vim/commit/bf269ed0b0bd8414eea7bea17465b2738a9a2b55

Code was reverted in patch 8.2.4638, so this just ports the test.
