that branch. You should instead write:
-

+You can give the `-m` flag to the command, which would try a
+three-way merge:
++
+------------
+$ git checkout -m mytopic

+After this three-way merge, the local modifications are _not_
+registered in your index file, so `git diff` would show you what
+changes you made since the tip of the new branch.

+. When a merge conflict happens during switching branches with
+the `-m` option, you would see something like this:

+files. Edit and resolve the conflict and mark it resolved with
