-
-By default, I and L are '\t' and '\n' respectively.  When '-z'
-flag is in effect, both I and L are '\0'.
-
-In each <mode>, <sha1> and <path> pair, left hand side describes
-the left hand side of what is being compared (<tree-ish> in
-git-diff-cache, <tree-ish-1> in git-diff-tree, cache contents in
-git-diff-files).  Non-existence is shown by having 000000 in the
-<mode> column.  That is, 000000 appears as the first <mode> for
-newly created files, and as the second <mode> for deleted files.
-
-Usually two <path> are the same.  When rename/copy detection is
-used, however, an "create" and another "delete" records can be
-merged into a single record that has two <path>, old name and
-new name.

 -z::
 	\0 line termination on input
 
--R::
-	Output diff in reverse.  This is useful for displaying output from
-	"git-diff-cache" which always compares tree with cache or working
-	file.  E.g.
-
-		git-diff-cache <tree> | git-diff-helper -R file.c
-
-	would show a diff to bring the working file back to what
-	is in the <tree>.
-
--M::
-	Detect renames.
-
--C::
-	Detect copies as well as renames.
-
 -S<string>::
 	Look for differences that contains the change in <string>.
