In my review of the earlier patch, I said I was fine with the octal 
constants, but on reflection, I'm not sure it's worth changing them just 
for the hell of it.  We'd probably get a patch from someone else later 
to change it back to symbolic constants.  Is there an actual coding 
style issue, or is this just a personal preference?
