(defmacro spacemacs|use-package-add-hook (name &rest plist)
"Add post hooks to `:init' or `:config' arguments of an existing
configuration.
In order to use this macro the variable `use-package-inject-hooks'
must be non-nil.
This is useful in the dotfile to override the default configuration
of a package.
Usage:
(spacemacs|use-package-add-hook package-name
[:keyword [option]]...)
:pre-init Code to run before the default `:init' configuration.
:post-init Code to run after the default `:init' configuration.
:pre-config Code to run before the default `:config' configuration.
:post-config Code to run after the default `:config' configuration.
In practice the most useful hook is the `:post-config' where you can
override lazy-loaded settings."
