Hi Colin,

As you noted it is not too strict :).

So best bet is to follow what you see elsewhere in GRUB 2 code base and 
follow that. Of course one could argue should conventions be followed 
more closely.

Just make it look clean and try to follow most of the rules. We will 
spot them for you if we see the reason :)

It is usually a good idea to review contents of patches beforehand and 
try to keep changes as minimal as possible.

Thanks,
