Subject: vim-patch:9.1.0835: :setglobal doesn't work properly for 'ffu' and
 'tsrfu'

Problem:  :setglobal doesn't work properly for 'ffu' and 'tsrfu' when
          the local value is set (after v9.1.0831)
Solution: Check os_flags instead of buffer option variable (zeertzjq).

closes: vim/vim#15980
