I think editors like to thrown in leading zeros. For example, you will 
notice that they never let you get away with saying something like .534. It 
has to be 0.534. Supposedly that's easier to read.

I didn't know octal was 0d. I bet they had to do that because of the other 
rule that you have to start with 0. 0o or 0O would be too hard to parse if 
they were to use o or O for octal. ;-)
