+Note that during `git rebase` and `git pull --rebase`, 'theirs' checks out
+the local version, and 'ours' the remote version or the history that is rebased
+against.
++
+The reason ours/theirs appear to be swapped during a rebase is that we
+define the remote history as the canonical history, on top of which our
+private commits are applied on, as opposed to normal merging where the
+local history is the canonical one.
+During merging, we assume the role of the canonical history’s keeper,
+which, in case of a rebase, is the remote history, and our private commits
+look to the keeper as “their” commits which need to be integrated on top
+of “our” work.

+Normal merging:
+------------
+local ---------abC <-- canonical history
