When switching workspaces with AC-left/right/up/down shortcuts, the workspace
wraps by default. That is, if I have a 2x2 workspace virtual desktop and
workspace 1 is active and I press AC-left, I end up on workspace 2 (instead of
moving nowhere). The behaviour can be changed using wrap_layout configuration
option, but it might be better to make it false by default. Another problem is
that the options wrap_layout and wrap_cycle are not very clearly documented and
not orthogonal in behaviour: if wrap_layout is true, wrap_cycle appears to have
no effect at all.


Reproducible: Always
Steps to Reproduce:
1. make the workspace layout 2x2
2. press A-C-left


Actual Results:  
I end up in workspace 2 (which is at the right side of workspace 1)

Expected Results:  
Stay at workspace 1
