vim-patch:8.1.2281: 'showbreak' cannot be set for one window

Problem:    'showbreak' cannot be set for one window.
Solution:   Make 'showbreak' global-local.
https://github.com/vim/vim/commit/ee85702c10495041791f728e977b86005c4496e8

Change in oneleft() is N/A as the relevant condition was removed
(has_mbyte is always true for Nvim, so the condition was always false;
see commit 73dc9e9).

Use wp over curwin for curs_columns().

Required for v8.2.2903 (otherwise test fails as it'll leave the global
option set).

N/A patches for version.c:

https://github.com/vim/vim/commit/91e22eb6e09ec384496fccde812072033fd9e616

Already ported in commit 43a874a.
