rebase -i: learn to rebase root commit
Teach git-rebase -i a new option --root, which instructs it to rebase the entire history leading up to <branch>. This is mainly for symmetry with ordinary git-rebase; it cannot be used to edit the root commit in-place (it requires --onto <newbase>). Commits that already exist in <newbase> are skipped. In the normal mode of operation, this is fairly straightforward. We run cherry-pick in a loop, and cherry-pick has supported picking the root commit since f95ebf7 (Allow cherry-picking root commits, 2008-07-04). In --preserve-merges mode, we track the mapping from old to rewritten commits and use it to update the parent list of each commit. In this case, we define 'rebase -i -p --root --onto $onto $branch' to rewrite the parent list of all root commit(s) on $branch to contain $onto instead.
