+       Detect moving lines in the file as well.  When a commit
+       moves a block of lines in a file (e.g. the original file
+       has A and then B, and the commit changes it to B and
+       then A), traditional 'blame' algorithm 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.
