This patch makes an editable location bar return to breadcrumb mode when {key Ctrl L} is pressed, but only if the location bar currently has focus. Otherwise, it will simply return focus to it as before.
This provides a slightly easier way to make the location bar return to breadcrumbs mode
Bonus points: `KDirOperator` toggles editable/breadbrtumbs with {key Ctrl L} as well, so this improves consistency.
