vim-patch:8.2.2518: 'listchars' should be window-local

Browse Source 
Problem:    'listchars' should be window-local.
Solution:   Make 'listchars' global-local. (Yegappan Lakshmanan, Marco Hinz,
            closes vim/vim#5206, closes vim/vim#7850)

Nvim already has this feature, but it implements :set listchars the same
as :setglobal listchars, which is incorrect. Vim's implementation of
:set listchars is correct: using :set listchars clears local value.
