Fixes https://github.com/jwiegley/use-package/issues/564
- New keywords `:custom (foo1 bar1) (foo2 bar2)` etc., and `:custom-face`.
+ NOTE: These are only for people who wish to keep customizations with their
+ accompanying use-package declarations. Functionally, the only benefit over
+ using `setq` in a `:config` block is that customizations might execute code
+ when values are assigned. If you currently use `M-x customize-option` and
+ save to a settings file, you do not want to use this option.
+
- New `:magic` and `:magic-fallback` keywords.
- New `:defer-install` keyword.
