The indentation is messed up. You should set your editor tab width to 8 instead of 4.
My apologies --- our internal coding standard has tabs set at 4 spaces - and I haven't figured out how to tell xemacs to use tabs of 8 spaces in some directories, and 4 spaces in others... I thought I had fixed any indentation issues in the patches I was submitting - guess I missed this one. I'll resubmit shortly...
