in the linkgit:git-log[1]
	manual page.

--contents <file>::
	Annotate using the contents from the named file, starting from <rev>
	if it is specified, and HEAD otherwise. You may specify '-' to make
	the command read from the standard input for the file contents.

--date <format>::
	Specifies the format used to output dates. If --date is not
	provided, the value of the blame.date config variable is
	used. If the blame.date config variable is also not set, the
	iso format is used. For supported values, see the discussion
	of the --date option at linkgit:git-log[1].

--[no-]progress::
	Progress status is reported on the standard error stream
	by default when it is attached to a terminal. This flag
	enables progress reporting even if not attached to a
	terminal. Can't use `--progress` together with `--porcelain`
	or `--incremental`.

-M[<num>]::
	Detect moved or copied lines within a file. When a commit
	moves or copies a block of lines (e.g. the original file
	has A and then B, and the commit changes it to B and then
	A), the traditional 'blame' algorithm notices only half of
	the movement and typically blames the lines that were moved
	up (i.e. B) to the parent and assigns blame to the lines that
	were moved down (i.e. A) to the child commit.  With this
	option, both groups of lines are blamed on the parent by
	running extra passes of inspection.
+
<num> is optional but it is the lower bound on the number of
alphanumeric characters that Git must detect as moving/copying
within a file for it to associate those lines with the parent
commit. The default value is 20.

-C[<num>]::
	In addition to `-M`, detect lines moved or copied from other
	files that were modified in the same commit.  This is
	useful when you reorganize your program and move code
	around across files.  When this option is given twice,
	the command additionally looks for copies from other
	files in the commit that creates the file. When this
	option is given three times, the command additionally
	looks for copies from other
