 --cached::
-       Display the SHA-1 stored in the index, not the SHA-1 of the currently

-       status command.
+       This option is only valid for status and summary commands.  These

+-n, --summary-limit::
+       This option is only valid for the summary command.
+       Limit the summary size (number of commits shown in total).
+       Giving 0 will disable the summary; a negative number means unlimited
