charset=UTF-8 Content-Transfer-Encoding: 8bit From: Kristoffer Haugsbakk This trailer comes up often enough and the use case is not fully covered by the other trailers here. For example, it is sometimes better to use this trailer instead of `Co-authored-by:`. Signed-off-by: Kristoffer Haugsbakk --- Notes (series): Note: “*can be* used”. Not “is”. Based on practical usage, I think it would be wrong to claim that someone sending a literal patch snippet via email means that this is the tag that you ought to use. I think e.g. `Helped-by` might be used instead. I also think that the “is” for `Helped-by` is too strongly worded for the same reasons.
