I’m still a bit perplexed by some behaviour seen today, and am looking for a clean way to deal with it that the documentation does not make clear. So, I’m asking in a different way. Suppose a graph of A---B---C---D---E \ \ / \----F—G----/ When trying to perform a format-patch from B to E, I was seeing commits B-A-F-G-E rather than what I wanted B-C-D-E. F and G were younger commits than C and D, which I assume (very likely wrongly) is why diff was giving preferential treatment to that path. What I am trying to figure out is whether there is a clean way to force format-patch along the B-C-D-E path. If not, would it be worth starting up a small project to make this possible (not knowing exactly where to start), but I would envision something like: git format-patch –via=C B..E I may be just missing something obvious (new to format-patch operations myself).
