+    --------------------------------------------------------
+    <xy>        The staged and unstaged values described earlier, with
+                unchanged indicated by a "." rather than a space.
+    <sub>       The submodule state. "N" when the entry is not a submodule.
+                "S[C][M][U]" when the entry is a submodule.
+                "C" indicates the submodule commit has changed.

+                "U" indicates the submodule has untracked changes.
+    <m*>        The file modes for the entry.
+                For unmerged entries, these are the stage 1, 2, and 3,
+                and the worktree modes.
+                For regular entries, these are the head, index, and
+                worktree modes; the fourth is zero.
+    <sha*>      The SHA1 values for the entry.
+                For unmerged entries, these are the stage 1,2, and 3 values.
+                For regular entries, these are the head and index values;

+
