[xmonad] "wmctrl -l" lists all my windows as being on the same workspace (0)

Hi Tobias,

Well, I would like to feed the output of "wmctrl -l" into an applet that would tell me which windows are on which workspace(s). This pretty much breaks any hope of getting that information precisely when it is most useful (ie, when one is using a multi-head setup and is likely to do even greater use of all the different workspaces).

I am pretty confident this worked fine in 0.9, because I used the Gnome Windows Selector back then and it could tell me on which workspace each window was.

Hey Lara,

hmm, you're correct, I noticed the same behaviour here. All windows from the
workspace on the "laptop screen" and all from the "external screen" are listed
as being on the currently active workspace, depending on "where my mouse cursor
is".

And yes, I also think this particular code snippet is responsible for this
behaviour.

Anyway, does this cause any problems? I haven't noticed any by now.
