-b::
	Show blank SHA-1 for boundary commits.  This can also
	be controlled via the `blame.blankBoundary` config option.

--root::
	Do not treat root commits as boundaries.  This can also be
	controlled via the `blame.showRoot` config option.

--show-stats::
	Include additional statistics at the end of blame output.

-L <start>,<end>::
-L :<funcname>::
	Annotate only the line range given by '<start>,<end>',
	or by the function name regex '<funcname>'.
	May be specified multiple times. Overlapping ranges are allowed.
+
'<start>' and '<end>' are optional. `-L <start>` or `-L <start>,` spans from
'<start>' to end of file. `-L ,<end>` spans from start of file to '<end>'.

-l::
	Show long rev (Default: off).

-t::
	Show raw timestamp (Default: off).

-S <revs-file>::
	Use revisions from revs-file instead of calling linkgit:git-rev-list[1].

--reverse <rev>..<rev>::
	Walk history forward instead of backward. Instead of showing
	the revision in which a line appeared, this shows the last
	revision in which a line has existed. This requires a range of
	revision like START..END where the path to blame exists in
	START.  `git blame --reverse START` is taken as `git blame
	--reverse START..HEAD` for convenience.

--first-parent::
	Follow only the first parent commit upon seeing a merge
	commit. This option can be used to determine when a line
	was introduced to a particular integration branch, rather
	than when it was introduced to the history overall.

-p::
--porcelain::
	Show in a format designed for machine consumption.

--line-porcelain::
	Show the porcelain format, but output commit information for
	each line, not just the first time a commit is referenced.
	Implies --porcelain.

--incremental::
	Show the result incrementally in a format designed for
	machine consumption.

--encoding=<encoding>::
	Specifies the encoding used to output author names
	and commit summaries. Setting it to `none` makes blame
	output unconverted data. For more information see the
	discussion about encoding 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
