+ This is necessary to use Git on Windows shared directories, and is

+ when merge begins.
+
+ * When "git merge" notices that the merge can be resolved purely at
+ the tree level (without having to merge blobs) and the resulting
+ tree happens to already exist in the object store, it forgot to
+ update the index, which lead to an inconsistent state for later
+ operations.
