+--rebase-merges::
+ By default, a rebase will simply drop merge commits from the todo
+ list, and put the rebased commits into a single, linear branch.
+ With `--rebase-merges`, the rebase will instead try to preserve
+ the branching structure within the commits that are to be rebased,
+ by recreating the merge commits. Any resolved merge conflicts or
+ manual amendments in these merge commits will have to be
+ resolved/re-applied manually.
++
+This mode is similar in spirit to `--preserve-merges`, but in contrast to
+that option works well in interactive rebases: commits can be reordered,
+inserted and dropped at will.
++
+It is currently only possible to recreate the merge commits using the
+`recursive` merge strategy; Different merge strategies can be used only via
+explicit `exec git merge -s <strategy> [...]` commands.

Recreate merge commits instead of flattening the history by replaying
The todo list presented by `--preserve-merges --interactive` does not
represent the topology of the revision graph. Editing commits and
rewording their commit messages should work fine, but attempts to
-reorder commits tend to produce counterintuitive results.
