Similar to the `preserve` mode simply passing the `--preserve-merges`
option to the `rebase` command, the `merges` mode simply passes the
`--rebase-merges` option.
This will allow users to conveniently rebase non-trivial commit
topologies when pulling new commits, without flattening them.

branch after fetching. If there is a remote-tracking branch
corresponding to the upstream branch and the upstream branch
was rebased since last fetched, the rebase uses that information
