Subject: vim-patch:8.2.3900: it is not easy to use a script-local function for
 an option

Problem:    It is not easy to use a script-local function for an option.
Solution:   recognize s: and <SID> at the start of the expression. (Yegappan
            Lakshmanan, closes vim/vim#9401)

https://github.com/vim/vim/commit/8bb65f230d3025037f34021a72616038da0601ee

Omit duplicate docs in fold.txt: removed in a later runtime update.
Cherry-pick test_diffmode.vim changes from patch 8.2.1432.
