+       Usually a three-way merge by `git-read-tree` resolves
+       the merge for really trivial cases and leaves other
+       cases unresolved in the index, so that Porcelains can
+       implement different merge policies.  This flag makes the

+  unmodified.  The resolution is to remove that path.
+* when both sides remove a path.  The resolution is to remove that path.
+* when both sides adds a path identically.  The resolution
+  is to add that path.
