Along with "git submodule", what about "git subtree"?

[rpjday]

Given the sizable section on submodules, would it not make sense to cover Git subtrees as well? (Given the length of Chapter 7, it might be useful to break up that chapter into smaller sections, with an entire chapter devoted to submodules/subtrees, but that's just a thought.)

That’s not a half-bad idea, actually, but a pretty big project.

There is actually a small section on subtrees, "Subtree Merging", in chapter 7.8 - Advanced Merging.
