Comment (by akibjorklund):

 [attachment:33704-focus.diff] handles autofocus-related usage of
 `wp_is_mobile()`. Turns out WordPress already has a mechanism for setting
 focus: you just add a class `wp-initial-focus` to an element. This was not
 used anywere. So I just tweaked that to only fire when `wpResponsive` is
 not active. Plus, on install.php, where common.js is not available, tested
 against the viewport width instead.
