<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>I18N: Allow the login screen language to be specified via a `wp_lang` query variable, and use this for the interim login modal.
This allows users who are using the admin area in a language other than the site language to read the notice on the login screen
(which explains that they need to log in again) in their chosen language.
