In fact on my pc, when there is no fg_end or fg_center defined,
it draws it one pixel too much on the right.
On Gigamo's PC, that patch should work on any case.
It also 'should' work from what I guess!
For people having a problem, they could define fg_end to the same as fg.
Or when it's really serious (on not just here), that could be done inside
awesome.
(Finally somekind of little cairo bug, from my perspektive)
