21422	Micro-optimization in admin-footer.php	TobiasBg	nacin	"After some work (related to the admin bar) on admin-footer.php in wp-admin a while ago ([18888], the latest change in the file), the file does some unnecessary stuff, like an implode() on a one-item array, that's constant and unchangable.

It's just minor, but still done on every page load in the Dashboard, so let's just micro-optimize it away.

The attached patch removes that unnecessary implode() and two local variables."	enhancement	closed	normal	3.5	Administration	3.3	trivial	fixed	has-patch commit
