Modeline is ignored on save if default values are set

[cprn]

Describe the bug When a default value is set, e.g. shiftwidth or foldmethod, the one from the modeline is ignored on save of init.lua.

To Reproduce On clean nvim with init.lua from kickstart.nvim:

1. in section with vim.o settings add:

vim.o.foldmethod = 'syntax'

2. in modeline append:

fdm=indent

3. save
4. :set fdm says syntax and not indent or manual (default)
5. reopen file with :e
6. :set fdm says indent
