That is, from the left to the right:
Example:
------------------------------------------------
-:100644 100644 5be4a4...... 000000...... M file.c
+:100644 100644 5be4a4a 0000000 M file.c
------------------------------------------------
Without the `-z` option, pathnames with "unusual" characters are
Example:
------------------------------------------------
-::100644 100644 100644 fabadb8... cc95eb0... 4866510... MM describe.c
+::100644 100644 100644 fabadb8 cc95eb0 4866510 MM describe.c
