In the previous patches, we implemented the basic functionality of the `git rebase -i --rebase-merges` command, in particular the `merge` command to create merge commits in the sequencer. The interactive rebase is a lot more these days, though, than a simple cherry-pick in a loop. For example, it calls the post-rewrite hook (if any) after rebasing with a mapping of the old->new commits. This patch implements the post-rewrite handling for the `merge` command we just introduced. The other commands that were added recently (`label` and `reset`) do not create new commits, therefore post-rewrite hooks do not need to handle them.
