patch 9.1.0069: ScreenLines may not be correctly initialized, causing hang
Problem: ScreenLines may not be correctly initialized, causing hang
(Olaf Seibert, after 9.0.0220)
Solution: always initialize ScreneLines when allocating a screen
(Olaf Seibert)
ScreenLines and related structures could be left uninitialized
causing a screen update to run into an infinite loop when using latin1
encoding.
Partly caused because by patch 9.0.0220, which makes mb_ptr2len return
zero for NUL
related: #12671
closes: #13946
