I'm not sure how well define it is to be honest. MAINTAINERS is focused
a bit too much on CCing people rather than code flow. Which hurts us in
more than one way. I _think_ the right way to find the responsible tree
is to do an longest prefix match on the path in MAINTAINERS, looking
just at the entries which have a T: attribute. (Q: attribute for that
entry may also be useful.) In practice I myself usually look at:

	git log --format=committer -- $path

where:

[pretty]
	committer = %<(20)%cn %cs  %<(47,trunc)%s
