Fix README.md

[dunmaksim]

Hello!

I saw README.md and fix some markdown errors.

Also use-package.el documentation says:

• :init

  Use the :init keyword to execute code before a package is loaded. It accepts one or more forms, up to the next keyword...

• :config:

  Similarly, :config can be used to execute code after a package is loaded. In cases where loading is done lazily (see more about autoloading below), this execution is deferred until after the autoload occurs.

Summary: you must turn on mode in :config section, not an :init.

This actually does work as expected because of the ;;;###autoload cookie prefixed to the minor mode definition. The :init form is run before the package is fully loaded, but the minor mode definition is apparently already in scope when the block runs because of the cookie.

See, for example, Corfu's documentation, which similarly suggests using the :init block.

The reason I suggest using the :init clause is because, although I want the mode to be enabled at startup, I don't want it to be enabled when re-evaluating my config file (possibly overriding the current value for the mode).

For example, with the following config:

(use-package magit-file-icons
  :ensure t
  :after magit
  :config
  (magit-file-icons-mode 1))

If I've disabled the mode at runtime, and now want to evaluate my config file with this form in it, the minor mode will be re-enabled, which is a bit annoying. Using :init avoids this problem.

Thanks for taking your time to improve the package! If my analysis is mistaken or you would like to add something to the previous, please let me know.

I would still like to accept the formatting changes to the README.
