Comment 10 for bug 826089

It doesn't appear Gnome is going to fix this anytime soon which may be too bad for some unity-2d users
The key is currently a simple way to adjust the number of Ws's unity-2d will use, intended or otherwise

Note on gnome bug report - Gs set the num value to however many workspaces are open in Gs when exiting, typically 1, but not limited to that by any means
