I'm not sure about this comment [0], it should likely be moderated simply for being overly complex. I think it's silly not to use a pastebin or even open a new package with the proposed updates temporarily, so everyone could benefit from the changes immediately. That said, I actually wonder whether the content can even be applied as a patch due to possible whitespace mangling.
