I'll just drop that bit of the description in favour of code readability. Hope you don't mind!

Patch is also wrong as that out is used by other gotos... I guess this is because it's dependent on the patch you sent later on Friday. I'll reorder, but please be careful of this in future. If patches are in separate series posted as the same time they really need to be independent.
