Hmm, Actually this looks awkward in the patches only due to me using 
spaces rather than tabs to indent in the new code (old code uses tabs).  
Not sure what the preferred strategy is here, use mesa coding style 
(spaces) or old dri coding style (tabs). If the latter, we should 
probably at some point add subsystem editor setup files that override 
the mesa default ones.
