+ Invoke an editor before committing successful mechanical merge to
+ further edit the auto-generated merge message, so that the user
+ can explain and justify the merge. The `--no-edit` option can be
+ used to accept the auto-generated message (this is generally
+ discouraged). The `--edit` option is still useful if you are

+user to edit the merge log message. They will see an editor opened when
+they run `git merge`. To make it easier to adjust such scripts to the
+updated behaviour, the environment variable `GIT_MERGE_AUTOEDIT` can be
+set to `no` at the beginning of them.
