+-L<start>,<end>:<file>::
+-L:<funcname>:<file>::
+
+	Trace the evolution of the line range given by '<start>,<end>',
+	or by the function name regex '<funcname>', within the '<file>'. You may
+	not give any pathspec limiters.  This is currently limited to
+	a walk starting from a single revision, i.e., you may only
+	give zero or one positive revision arguments, and
+	'<start>' and '<end>' (or '<funcname>') must exist in the starting revision.
+	You can specify this option more than once. Implies `--patch`.
+	Patch output can be suppressed using `--no-patch`, but other diff formats
+	(namely `--raw`, `--numstat`, `--shortstat`, `--dirstat`, `--summary`,
+	`--name-only`, `--name-status`, `--check`) are not currently implemented.
