+A series of lines are then displayed for the tracked entries.
+Ordinary changed entries have the following format:
+
+    1 <XY> <sub> <mH> <mI> <mW> <hH> <hI> <path>
+
+Renamed or copied entries have the following format:

+    <XY>        A 2 character field containing the staged and
+                unstaged XY values described in the short format,
+                with unchanged indicated by a "." rather than
+                a space.
+    <sub>       A 4 character field describing the submodule state.
+                "N..." when the entry is not a submodule.
+                "S<c><m><u>" when the entry is a submodule.
+                <c> is "C" if the commit changed; otherwise ".".
+                <m> is "M" if it has tracked changes; otherwise ".".
+                <u> is "U" if there are untracked changes; otherwise ".".
+    <mH>        The 6 character octal file mode in the HEAD.
+    <mI>        The octal file mode in the index.
+    <mW>        The octal file mode in the worktree.
+    <hH>        The SHA1 value in the HEAD.
+    <hI>        The SHA1 value in the index.
+    <X><nr>     The rename or copied percentage score. For example "R100"
+                or "C75".
+    <path>      The current pathname.
+    <pathSrc>   The original path. This is only present when the entry
+                has been renamed or copied.

+
+Unmerged entries have the following format; the first character is
+a "u" to distinguish from ordinary changed entries.

+    <XY>        A 2 character field describing the conflict type
+                as described in the short format.
+    <sub>       A 4 character field describing the submodule state
+                as described above.
+    <m1>        The octal file mode for stage 1.

+
+A series of lines are then displayed for untracked and ignored entries.
+
+    <x> <path>
+
+Where <x> is "?" for untracked entries and "!" for ignored entries.
+
+In all 3 line formats, pathnames will be "C Quoted" if they contain
+any of the following characters: TAB, LF, double quotes, or backslashes.
+These characters will be replaced with \t, \n, \", and \\, respectively,
+and the pathname will be enclosed in double quotes.
+
+When the `-z` option is given, a NUL (zero) byte follows each pathname;
+serving as both a separator and line termination. No pathname quoting
+or backslash escaping is performed. All fields are output in the same
+order.
