Code review comment for lp:~a-j-buxton/ubiquity/struts

I just noticed that my patch won't actually work because set_strut tries to force LEFT to be not zero here:

http://bazaar.launchpad.net/~ubuntu-installer/ubiquity/trunk/view/head:/src/panel/panel.c#L71

So the result is with this patch the struts won't be set at all.
