vim-patch:8.2.1489: Vim9: error when setting an option with setbufvar()

Browse Source 
Problem:    Vim9: error when setting an option with setbufvar().
Solution:   Do not get a number from a string value. (closes vim/vim#6740)
191929b182

Vim9 is N/A, so this just refactors the code without changing behavior.
