-- per-filetype options harvested from the builtin vimscript ftplugins
-- ( nvim 0.12, before the ftplugin kill ) then filtered to pure-data options.
-- deliberately dropped: omnifunc ( LSP owns it ), includeexpr ( vimscript/autoload ),
-- cinkeys/cinwords ( cindent is off, treesitter indents ).
-- commentstring lives in std.commentstring. edit freely.
