-       Rebase the current branch on top of the upstream branch after
-       fetching.  If there is a remote-tracking branch corresponding to

+When preserve, also rebase the current branch on top of the upstream
+branch, but pass `--preserve-merges` along to `git rebase` so that
+locally created merge commits will not be flattened.
++
+When false, merge the current branch into the upstream branch.
