[xmonad] Controlling Window Location with XMonad.Layout.ThreeColumns

[Brent Yorgey]

Hi Eyal,

I'm just going back through old xmonad emails trying to make sure nothing
falls through the cracks.  Would you mind creating an issue for this at
https://github.com/xmonad/xmonad-contrib/issues ?  I am not yet confident I
understand what is going on here well enough to know what the right fix is,
but if a ticket is created then it becomes easier for others to look at it,
and it won't accidentally be forgotten.  Thanks!

-Brent
