 The attached patch adds an action hook in the automatic (background)
 upgrading process.

 I have a need for such a hook in a plugin. (I wish to record some state
 information pre-update). Currently, if you want to do this, then it's very
 ugly and hackish: the nearest you can get is to use the should_update
 filter, and duplicate part of the WP_Automatic_Updater::should_update()
 method within your filter (the part that comes after the filter is called
 - because that can also prevent the update). And even so, it's a filter:
 someone else might decide to call it for a different reason other than a
 real update going ahead, so, you've also got to do stuff with
 doing_action() to make sure of your context.
