I just upgraded to Wily yesterday, and it seems this regression has crept up again (it happened around the Utopic timeframe too).
Install Byobu.
sudo apt-get install byobu
Open from the Unity Launcher. Press Windows icon. Type 'byobu'. Click on the Ubuntu terminal icon. Byobu open in the default terminal (as specified in the byobu.desktop file), but the icon on the left in the unity bar is the Terminal icon, not the Byobu one.
