Add :magic and :magic-fallback keywords (issue)
These keywords work equivalently to `:mode` or `:interpreter`, but for `magic-mode-alist` and `magic-fallback-mode-alist`. The handler function implementation is now passed a list to add to, and shared by all four of them. GitHub-reference: https://github.com/jwiegley/use-package/issues/469
