- 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), the 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.
