wp_title outputs separator for empty title

It appears that  caused some changes in how wp_title works; specifically, the separator is returned even when no title exists (e.g. on the blog home page). For example:

Additionally the $posts global (used in the is_single() || is_page() branch) was removed from the list, which broke titles in additional cases.
