Yes, the patch-id is a heuristic. It's really a very good heuristic in practice, though. Also, if the argument is "it might not always work", I still claim that "99.5% useful" is a hell of a lot better than "_maybe_ useful in the future, but known to be painful". Because that's the trade-off here: people are arguing for something that wastes time and effort, and with very dubious use cases. But yes: please do continue to add links to the original email - IF you thought about it. That has always been my standpoint. Exactly like "Fixes", and exactly like EVERY SINGLE OTHER THING you add to a commit message. Linus
